Van Life Glossary

An A-frame is a rigid triangular towing bar that attaches to the front of a car being towed flat (all four wheels on the ground) behind a motorhome, without using a trailer or dolly.

A-frame towing requires the towed vehicle to have a flat-tow rating from the manufacturer. Popular among full-time motorhome travelers in North America. Legal in most US states; regulations vary across Europe.

The ADAC (Allgemeiner Deutscher Automobil-Club) is Europe's largest motoring association with over 20 million members. Beyond roadside assistance, it conducts respected annual motorhome and caravan tests, rates campsite quality and publishes the ADAC Campingführer guide.

The annual ADAC motorhome test assesses safety, habitability and build quality and is among the most-cited reviews in Europe. The ADAC Camping app lists 8,000+ pitches. Membership provides discounts at partner campsites. Test results are freely available at ADAC.de.

An AGM (Absorbed Glass Mat) battery is a sealed lead-acid battery where the electrolyte is held in glass mat separators, making it spill-proof, low-maintenance, and suitable for motorhome use.

AGM batteries provide around 50–60% usable capacity and 400–600 charge cycles. They tolerate vibration and can be mounted in any orientation except inverted. Better performance than standard flooded batteries but inferior to LiFePO4 for deep-cycle use.

AL-KO (Alois Kober) is a German manufacturer of caravan and trailer chassis, hitching systems, stabilisers, wheel locks, and the ATC (Automatic Trailer Control) electronic anti-sway system.

The AL-KO chassis underpins the majority of European caravans. The AL-KO ATC system detects snaking and applies the trailer's brakes automatically. AL-KO also produces the DWS (Driving Safety Systems) weight distribution hitches and the Secure wheel lock.

An absorption fridge is a silent refrigerator that uses heat (from LPG gas, 230V mains, or 12V DC) to drive a cooling cycle with no moving parts. The three-power capability makes it standard in European motorhomes.

Absorption fridges must be kept reasonably level (within ±6°) to function correctly — hence the need for levelling ramps. They cool slowly and are less efficient than compressor fridges but can run indefinitely on LPG gas when off-grid.

An accumulator tank is a small pressure vessel connected to the water pump circuit that stores pressurised water, smoothing flow, reducing pump cycling, and extending pump life.

Without an accumulator, the pump starts every time a tap is opened (even for a tiny flow). With one, the pump runs only when the pressure drops below a set threshold, reducing noise and wear. Typically 0.5–2 litres in size.

An aire is a designated motorhome parking area in France and other countries offering free or low-cost overnight parking with basic facilities such as fresh water, waste disposal, and sometimes electricity.

France has over 4,000 aires, listed on apps like Park4Night and Camping-Car Park. Many are free; some charge €5–15 per night. The Camping-Car Park network has industrialised many traditional free aires.

Airstream is an American manufacturer of distinctive riveted aluminium travel trailers and motorhomes founded by Wally Byam in 1931. Its polished silver barrel-shaped silhouette is one of the most recognisable icons of American camping culture.

Airstream's towable lineup includes Flying Cloud, Bambi, Classic and International. The company also produces Class B motorhomes (Interstate, Atlas) on Mercedes-Benz Sprinter platforms. Vintage 1960s–70s Airstreams command premium prices on the used market due to their cult status.

An alcove motorhome (Alkoven in German) is a coachbuilt body with a sleeping area that extends over the driver's cab, providing an extra double berth above the cab without increasing the vehicle's overall length.

Alcove motorhomes are popular with families who need the extra sleeping space. The overhead berth is typically accessed via a ladder or steps. These vehicles are taller than semi-integrated models and may be restricted in some low-clearance car parks.

Aqua Kem is Thetford's range of chemical treatments for cassette toilets and black water holding tanks, designed to break down waste, control odour, and lubricate the blade valve.

Available in liquid (Aqua Kem Blue, Green) and drop-in tablet form. The "Green" formula is biodegradable and approved for grey water disposal in some countries. Use about 100ml per cassette filling. Do not mix different brands.

An awning is a retractable shade structure attached to the side of a motorhome or caravan that extends outward to create a covered outdoor living area, providing shelter from sun and light rain.

Awnings may be manual (rolled out by hand) or electric. Drive-away awnings allow the motorhome to be moved while leaving the awning standing. Popular brands include Thule, Fiamma, and Omnistor.

A Battery Management System (BMS) is an electronic circuit that protects lithium battery cells from overcharging, over-discharging, overcurrent, and overheating, and balances cell voltages to maximise battery life.

Every lithium (LiFePO4) leisure battery includes a BMS, either built-in or external. The BMS disconnects the battery if any cell goes out of safe range. A good BMS also provides state-of-charge data via Bluetooth or CAN bus.

A berth is a designated sleeping space in a motorhome or caravan. Berths may be fixed (always set up as a bed) or convertible (a dinette or lounge that folds into a sleeping area). The number of berths is a key motorhome specification.

A "4-berth" motorhome sleeps four people. Fixed berths are more convenient; convertible berths save space during the day. Many motorhomes combine a fixed rear double bed with convertible front berths for the best of both.

Black water is waste water from the motorhome or RV toilet, containing human waste. In North American RVs this is collected in a black water tank; in European motorhomes toilet waste typically goes into a cassette.

Black water must be disposed of only at authorised dump stations or service points. Never discharge into drains, rivers, or on the ground. In the USA, BLM land and most campgrounds have designated dump stations.

Boondocking is an American term for camping in an RV or van without any hookups (electricity, water, or sewer), typically on public land managed by the Bureau of Land Management (BLM) or U.S. Forest Service.

The term is used primarily in North America. In Europe, the equivalent practice is called "wild camping" or "free camping." Boondockers rely on solar panels, water tanks, and composting toilets for self-sufficiency.

The CEE connector (IEC 60309, also called "blue commando") is the standard blue 16A or 32A circular plug used for mains hook-up at European campsites and motorhome service points.

The 16A blue CEE plug is the most common campsite connection. It is weather-proof and polarised — it can only be inserted one way. The camping cable from the motorhome has a male CEE plug (to site post) and a female socket (to motorhome inlet).

A campervan is a van that has been converted or factory-built to include sleeping and basic living facilities, typically based on light commercial vans such as the Volkswagen Transporter, Mercedes Sprinter, or Fiat Ducato.

Campervans are smaller and more maneuverable than large motorhomes, making them popular for solo travelers and couples. The term is used interchangeably with "camper" in North America.

A caravan is a towable recreational vehicle designed to be pulled by a car or SUV, providing sleeping and basic living facilities without its own engine. Also called a "trailer" in North America.

Modern caravans feature full kitchens, wet rooms, and sophisticated heating systems. Popular brands include Hobby, Dethleffs, Caravelair, and Bailey. EU Directive 94/20/EC governs coupling requirements.

A caravan park (also campsite or campground) is a managed site with marked pitches for motorhomes, campervans and caravans, equipped with shared facilities such as electrical hookups, water, toilets, showers and laundry.

European campsites are rated 1–5 stars (ADAC, ECOCAMPING) ranging from basic stopovers (€5–15/night) to five-star holiday resorts with pools (€80+). Booking platforms include ACSI, Pitchup and Camping Key Europe.

A cassette toilet is a motorhome toilet with a fixed bowl connected to a removable waste cassette (typically 15–21 litres) that can be carried to a public toilet or dump point for emptying.

The Thetford C200 and C250 are the most common European cassette toilet models. The cassette includes a level indicator, blade valve, and folding handle for transport. Chemical additives control odour.

A coachbuilt motorhome has a separately manufactured body (typically made of composite fibreglass or sandwich panels) fitted to a commercial van chassis. Includes semi-integrated, fully integrated, and overcab body styles.

Coachbuilt motorhomes are built by specialist converters using a rolling chassis and cab unit from manufacturers like Fiat, Ford, or Mercedes. The construction allows lightweight, well-insulated bodies.

A composting toilet is a waterless, chemical-free toilet system for campervans and motorhomes that separates solid and liquid waste to enable aerobic composting of solids — requiring no chemical flush fluid and no sewage connection.

Liquid waste drains to a removable bottle; solids are mixed with coconut fibre or wood chips to decompose aerobically. Popular brands: Nature's Head, Airhead, C-Head. The compost compartment typically needs emptying every 4–8 weeks depending on use.

A compressor fridge uses a motor-driven compressor (similar to a household fridge) running on 12V or 24V DC, offering faster and more efficient cooling than absorption fridges and working at any angle.

Compressor fridges are more energy-efficient and cool faster than absorption models, but consume 12V power continuously (typically 3–8 Ah/hour). They are preferred in van conversions and van life setups with solar charging.

A DC-DC charger (battery-to-battery charger) is a device that takes power from the vehicle's alternator (via the starter battery) and steps it up to the correct voltage to efficiently charge the leisure battery while driving.

DC-DC chargers are essential for LiFePO4 batteries, which simple split-charge relays cannot charge correctly. They also protect the starter battery from being drained. Popular models include the Victron Orion-Tr Smart and Sterling B2B.

A diesel heater is an independent heating system that burns diesel fuel (drawn from the vehicle's fuel tank) to produce warm air for the living area, without requiring mains electricity or gas.

Popular for off-grid camping in cold climates. They are quiet, fuel-efficient, and safe to use indoors. The two main European brands are Webasto and Eberspächer. Lower-cost alternatives include Vevor and Autoterm.

A dinette is a booth-style seating area in a motorhome or caravan featuring a fixed table flanked by facing bench seats, which typically converts into a bed by lowering the table to seat level.

The dinette is one of the most common motorhome layouts. Conversion typically takes 2–3 minutes. Some modern motorhomes replace the traditional dinette with a fixed island bed and a separate lounge area.

Dometic is a Swedish manufacturer that is the world's largest supplier of motorhome and caravan equipment, including absorption and compressor fridges, air conditioning units, awnings, toilets, water heaters, and ventilation.

Dometic brands include Waeco (portable coolers), Seitz (windows and vents), and Kampa (awnings). The Dometic RM- and RML-series absorption fridges are fitted in millions of European motorhomes. Dometic acquired Alde (heating), Hartal (doors), and many others.

The Dometic Heki is a panoramic polycarbonate skylight/rooflight for motorhomes and caravans, providing natural light and ventilation. It is one of the most recognised accessories in the European motorhome market.

The Heki range includes standard and plus sizes, with built-in roller blind and flyscreen. The Heki Style features a solar panel integrated into the frame. They are sold as standard or aftermarket add-ons on millions of European motorhomes.

A dump station is a facility at campgrounds or service areas where RV black water tanks and motorhome toilet cassettes can be emptied safely into the sewage system.

In the USA, dump stations are provided free or for a small fee at most BLM areas, national parks, and truck stops. In Europe, motorhome service points (aires) typically include a cassette emptying facility.

EcoFlow is a Chinese manufacturer of portable power stations and home energy storage systems, founded in 2017. Its products are widely used by van lifers for their fast charging (X-Stream technology), high capacity and solar panel compatibility.

Key lines: River 2 (256–768 Wh), DELTA 2 (1024 Wh), DELTA Pro (3600 Wh), DELTA Pro Ultra (6144 Wh). X-Stream technology charges the DELTA 2 from a wall outlet in under 80 minutes. Competitors: Bluetti, Jackery, Goal Zero.

Electric hook-up (EHU) is the cable and connection system that links a motorhome or caravan to a campsite's mains electricity supply, providing 230V power for appliances and battery charging.

UK campsites typically provide 10A or 16A supplies via a blue CEE connector. Always use a correctly rated outdoor extension cable with RCD protection. Most campsite hook-up points include a built-in RCD.

An electric motorhome is an RV or campervan powered entirely by a battery-electric drivetrain rather than an internal combustion engine. The first production models entered the market in 2021–2023.

Key models include Fiat E-Ducato-based conversions, the Volkswagen ID. Buzz California (2024) and Thor Sequence (USA, 2023). Challenges include limited range (150–350 km), long charging times and the additional drain of habitation systems on the traction battery. A rapidly evolving segment.

An expedition vehicle is a purpose-built or heavily modified vehicle for extended off-road travel and remote camping, featuring a 4WD chassis, reinforced body, high ground clearance, and extended fuel and water capacity.

Common base vehicles include Mercedes Unimog, MAN TGE, Land Rover Defender, and Toyota Land Cruiser. They are used for overlanding across Africa, the Silk Road, or the Americas where road infrastructure is limited.

Fiamma is an Italian manufacturer of motorhome and caravan accessories, best known for its roll-out awnings (F45, F65 series), bike carriers (Carry-Bike), roof boxes, and steps.

Fiamma awnings are available in manual (F45) and electric (F65) versions in lengths from 2 to 5 metres. The F45 is the most common aftermarket awning in Europe. Fiamma also produces cargo bars, privacy rooms, and van conversion accessories.

The Fiat Ducato is an Italian light commercial van that has become the dominant chassis platform for European motorhomes and campervans — over 70% of European motorhomes are built on the Ducato or its rebadged variants (Citroën Jumper, Peugeot Boxer).

The current Ducato generation (X290, from 2014) is available with 2.2 MultiJet diesel engines from 120–180 hp. Standard wheelbases: L3 (3.75 m) and L4 (4.035 m). The electric E-Ducato launched in 2022 serves as the base for the first electric motorhome conversions.

A fifth wheel is a large towable recreational vehicle that connects to a specially designed hitch mounted in the bed of a pickup truck via a kingpin coupling, rather than a standard ball hitch.

Fifth wheels offer more living space than standard caravans and are more stable when towing due to the over-axle connection point. They require a pickup truck with a fifth-wheel hitch installed in the truck bed.

Free camping (also called wild camping) is the practice of camping or parking an RV or campervan overnight in a natural or public area without paying a fee, outside of commercial campsites.

Regulations vary by country: some countries (e.g. Germany, France) generally prohibit wild camping, while others (e.g. Spain, Portugal, many Eastern European countries) are more permissive. Always check local laws before free camping.

A fresh water tank is the fixed tank in a motorhome or caravan that stores potable water for drinking, cooking, and washing, filled at campsites, service points, or fresh water taps.

Fresh water tanks range from 20L to 200L depending on vehicle size. Drain and dry the tank when not in use to prevent bacterial growth. Some van lifers use portable jerry cans instead of fixed tanks for flexibility.

Frost Control is an automatic low-level heating mode in Truma heating systems that activates when the interior temperature drops near freezing, preventing water pipes, tanks, and pumps from freezing in winter storage or cold overnight temperatures.

Frost Control operates at a minimum setting (around 5°C) using minimal gas. It requires the heating system to be running in standby mode. For long-term winter storage without gas, the correct approach is full winterization (draining all water systems).

A full hookup pitch provides all three utility connections simultaneously: electricity (shore power), fresh water supply, and sewer drain or grey water disposal, eliminating the need to visit service points.

Full hookup pitches are standard at American RV parks and increasingly common at premium European campsites. They cost typically €5–15 more per night than a basic pitch and are especially useful for long stays.

A fully integrated motorhome is one in which the driver's cab is completely integrated into the living area, sharing the same wall, floor, and ceiling, with no separation between cab and salon.

Fully integrated motorhomes offer maximum living space and panoramic windshields. Popular brands include Dethleffs, Hymer, Knaus, and Carthago. They are the largest and most luxurious motorhome class, typically over 7 metres long.

A gas cylinder is a portable pressurised steel or aluminium container filled with LPG (propane or butane), used to supply gas appliances in motorhomes and caravans.

Cylinder sizes range from 1kg camping canisters to 47kg exchange bottles. Exchange schemes (Calor in the UK, Campingaz across Europe) allow swapping empty for full. Refillable cylinders (Gaslow, Alugas) offer cost savings.

A gas regulator is a device fitted to a gas cylinder that reduces the high pressure of LPG to a constant low working pressure (28–50 mbar) suitable for motorhome appliances.

Regulators must match the gas type (propane or butane) and country standard. UK appliances use 28–30 mbar; much of continental Europe uses 50 mbar. Replace regulators every 10 years and change type when crossing borders if needed.

Glamping (glamorous camping) is a form of nature-based tourism that combines the outdoor experience with hotel-level comfort — fully equipped tents, geodesic domes, treehouses, yurts or boutique caravans with beds, electricity and en-suite bathrooms.

The global glamping market is valued at over $5 billion annually and growing at 14% per year. Popular formats include safari tents in Africa, transparent bubble tents in Europe and luxury trailer resorts in the USA. European bookings are dominated by Glamping Hub, Pitchup and Airbnb.

Grey water is used water from sinks, showers, and appliances (but not toilet waste) that is collected in a grey water tank or drains from the motorhome and must be disposed of at designated waste points.

In most European countries it is illegal to dump grey water on the ground or into drains. Grey water tanks range from 20L to 130L. Enzyme additives help reduce odours and break down organic matter.

Gross Train Weight (GTW) is the maximum permitted combined weight of a towing vehicle plus its attached trailer or caravan when fully laden. Exceeding GTW is illegal and invalidates insurance.

GTW = towing vehicle GVW + caravan MTPLM. The GTW rating is found in the tow vehicle's handbook. Always verify both the GTW and towing capacity limits before purchasing a caravan.

A hardstanding pitch is a campsite pitch with a hard surface (concrete, asphalt, gravel, or resin-bound), rather than grass, allowing use in wet weather without the motorhome becoming stuck in soft ground.

Hardstanding pitches are essential in rainy climates and are standard on UK Certificated Locations (CLs) and most German Stellplätze. Grass pitches are softer and quieter but can become unusable after heavy rain.

A hitch is the coupling mechanism on the caravan or trailer drawbar that attaches to the tow ball on the towing vehicle. In North American usage "hitch" can also refer to the receiver or tow bar assembly.

European hitches are typically 50 mm ball couplings (AL-KO, BPW). They include friction stabiliser pads or an electronic stabiliser (AL-KO ATC) to prevent sway. Match hitch rating to the caravan's nose weight and GTW.

Hymer is a leading German motorhome and campervan manufacturer, founded in 1923 in Bad Waldsee. It is the flagship brand of the Erwin Hymer Group (EHG), Europe's largest motorhome manufacturing conglomerate, which includes Bürstner, Carado, Dethleffs and Niesmann+Bischoff.

EHG was acquired by US company Thor Industries in 2019. Hymer's flagship lines include the integrated B-Klasse (produced since 1971), the ML-T and Van campervans on Mercedes Sprinter, and the Eriba caravan brand. The Bad Waldsee facility produces approximately 50,000 units per year.

An inverter is an electronic device that converts 12V or 24V DC battery power into 230V AC mains power, allowing the use of household appliances (laptops, coffee machines) when off-grid without a generator.

Pure sine wave inverters are recommended for sensitive electronics. Modified sine wave inverters are cheaper but can damage some devices. A 300W inverter draws approximately 25A at 12V — monitor battery state carefully.

An inverter-charger is a device that combines a pure sine wave inverter (DC to AC) and a mains battery charger (AC to DC) in one unit, automatically switching between off-grid inverter mode and shore-power charging mode.

Inverter-chargers are the heart of sophisticated motorhome electrical systems. The Victron MultiPlus is the market standard, available in 12V or 24V versions from 500VA to 5kVA. They often include an integrated transfer switch.

A jockey wheel is a small castor wheel mounted on the front of a caravan or trailer drawbar that supports its weight when the trailer is unhitched and allows it to be manoeuvred by hand on flat surfaces.

Jockey wheels retract or swing up when hitched. Most have a screw mechanism for height adjustment. A quality jockey wheel with a wide rubber wheel makes hand-manoeuvring on gravel or grass much easier. Can be combined with a clamp for quick release.

Kastenwagen is a German term for a motorhome built within the body of a high-roof panel van, without a coachbuilt extension. The van's original metal bodywork is retained; the interior is fully fitted out.

Kastenwagen motorhomes are compact, garage-friendly, and more discreet than coachbuilt models. Popular base vans include the Fiat Ducato L3H2/H3, Mercedes Sprinter, and VW Crafter. Standing height is possible in models with raised roofs.

Kerbweight is the weight of a vehicle with standard equipment, full fuel tank, and all fluids, but without driver, passengers, or luggage. Used as the basis for calculating towing capacity.

The Caravan and Motorhome Club recommends caravans should not exceed 85% of the tow vehicle's kerbweight. Experienced towers may tow up to 100% of kerbweight within the vehicle's stated towing limit.

LPG is a mixture of propane and butane stored under pressure in cylinders or tanks, used in motorhomes and caravans for cooking, heating, and refrigeration. The most common fuel for motorhome appliances.

LPG cylinders must be stored in a sealed, externally vented locker. Butane is unsuitable below 5°C; propane works to −40°C. Fixed LPG tanks (autogas) allow refuelling at petrol stations across Europe.

A leisure battery is a secondary battery in a motorhome or caravan, separate from the vehicle starter battery, designed to power 12V appliances (lighting, water pump, heating fan) while camping without the engine running.

Leisure batteries are rated in amp-hours (Ah). A 100Ah lead-acid battery provides roughly 50Ah usable; a 100Ah LiFePO4 lithium battery provides 80–100Ah. Charged via alternator, solar panels, or mains hook-up.

Levelling ramps are plastic or rubber wedge-shaped blocks placed under motorhome or caravan wheels to compensate for uneven ground, ensuring the vehicle is level for sleeping comfort and correct appliance operation.

A level motorhome is essential for 3-way refrigerators to work correctly and for comfortable sleeping. Many van lifers carry a spirit level to check. Some modern motorhomes feature built-in electronic auto-levelling jacks.

LiFePO4 (lithium iron phosphate) is the safest and most popular lithium battery chemistry for motorhome leisure use, offering 80–100% usable capacity, 2,000+ charge cycles, and no memory effect.

A 100Ah LiFePO4 battery weighs around 12–14 kg vs. 25–30 kg for a comparable lead-acid. It charges 4× faster and maintains voltage under load. Requires a lithium-compatible charger (not all B2B chargers are compatible) and a BMS.

MIRO is the weight of a motorhome as built and ready to drive: standard equipment, full fuel tank, and 75 kg for the driver, but without passengers or personal belongings.

MIRO is the baseline for calculating payload. Payload = MTPLM − MIRO. Options and accessories added by the dealer increase MIRO and reduce available payload. Always check the actual MIRO on the vehicle's VIN plate.

An MPPT (Maximum Power Point Tracking) charge controller is a device that sits between solar panels and batteries, continuously adjusting its operating point to extract the maximum available power from the panels at any light condition.

MPPT controllers are 10–30% more efficient than simpler PWM controllers, especially in low light or when panel voltage differs significantly from battery voltage. Popular brands include Victron, Renogy, and Epever. Size by total panel wattage and battery voltage.

MTPLM is the maximum total weight of a motorhome or caravan, including all passengers, luggage, and equipment, as specified by the manufacturer and shown on the VIN plate.

Exceeding MTPLM is illegal and invalidates insurance. Motorhomes over 3,500 kg MTPLM require a Category C1 driving licence in Europe. The figure appears in the vehicle registration document and handbook.

A mosquito net or insect screen is a fine mesh fitted to windows, doors, and roof vents of a motorhome or campervan to prevent insects from entering while allowing air to circulate.

Quality screens use fibreglass or polyester mesh. Many motorhome windows have integrated insect screens (behind the pleated blind). For van conversions, custom screens are available from Seitz, Remis, and specialist converters.

A motorhome is a self-propelled recreational vehicle that combines a living area with the engine and driving cab in one integrated unit, available in Class A (bus-style), Class B (campervan), and Class C (cab-over) configurations.

Unlike towable trailers, a motorhome requires no separate tow vehicle. Popular motorhome brands include Hymer, Bürstner, Carthago, Chausson, and Fiat Ducato-based conversions.

A motorhome service area is a dedicated facility providing fresh water filling, waste water dumping, and toilet cassette disposal, installed at campsites, petrol stations, or dedicated motorhome stopovers.

Service areas may be coin-operated, token-operated, or app-controlled (e.g. Camping Key Europe). Costs range from free to €5 per use. The Flot Bleu network is the largest in France; similar networks operate across Germany, Spain, and Portugal.

A motorhome service point is a dedicated facility offering fresh water filling, waste water disposal, toilet cassette emptying, and sometimes electrical hook-up, found at aires, campsites, and service areas.

The Flot Bleu network operates over 1,500 service points in France alone. Access is typically via tokens, contactless cards, or the Camping Key app. Costs range from free to €5 per use.

A mover is a battery-powered motorised roller system fitted to caravan or motorhome wheels that allows the vehicle to be manoeuvred precisely on site using a remote control, without needing the engine or a second person.

Movers are most useful for tight pitches, reversing onto narrow strips, or positioning in low-ceilinged storage facilities. Popular brands include Truma, Reich, and Powrtouch. They draw significant 12V current during use and need a well-charged leisure battery.

Noseweight is the downward force exerted by a caravan or trailer's coupling on the tow ball of the towing vehicle, measured in kilograms. Correct noseweight is essential for safe, stable towing.

The recommended noseweight is 5–7% of the trailer's laden weight, within the limits in both the tow vehicle and caravan handbooks. Too little causes snaking; too much causes steering and braking problems.

Off-grid describes an RV or campervan operating entirely without an external electrical hookup, mains water or sewage connection — relying solely on onboard resources: solar panels, batteries, water tanks and a composting or cassette toilet.

A typical off-grid setup includes 200–600 W of solar panels, 100–400 Ah of LiFePO4 battery capacity, a 1–3 kW inverter and 100–200 litres of fresh water. A well-designed system allows weeks of comfortable camping outside established sites.

An overcab motorhome is a coachbuilt body fitted to a van chassis that includes a sleeping area above the cab. In Europe it is called "low-profile"; in North America the overcab bed projects forward to form Class C.

Overcab motorhomes maximise sleeping capacity by using the space above the cab. They are slightly taller than semi-integrated models but still fit in most campsites.

Overlanding is a style of self-reliant, long-distance vehicle-based travel across remote terrain — typically by 4×4 or expedition vehicles — where the journey itself is the primary goal rather than a specific destination.

Overlanders prioritise vehicle preparation: lifted suspension, winches, snorkels, extended fuel capacity (300+ litres) and expedition-grade rooftop tents. Popular routes include trans-African tracks, the Silk Road through Central Asia and the Pan-American Highway.

Payload is the maximum weight of passengers, personal belongings, food, water, and accessories that can be loaded into a motorhome or caravan, calculated as MTPLM minus MIRO.

Payload is often surprisingly low — some motorhomes have only 50–150 kg despite a 3,500 kg MTPLM. Water weighs 1 kg per litre; a full 100L tank adds 100 kg. Always weigh the loaded vehicle before travelling.

A pop-up camper is a lightweight towable trailer with collapsible roof and sides that fold up at the campsite to create sleeping and living space, reducing towing height and wind resistance on the road.

Pop-up campers are the lightest and most affordable towable option. When folded, they typically stand around 1 metre high, making them easy to tow with smaller cars. Popular brands include Combi-Camp and Raclet.

An RCD is a safety device that automatically disconnects the electrical supply if it detects current leaking to earth (indicating a fault or electric shock hazard), required on all campsite hook-up supplies.

RCDs are mandatory for campsite hook-up connections in most European countries. They trip within 30 milliseconds of detecting a 30mA fault. Many motorhome mains systems include a built-in RCD in the hook-up socket.

RV is a broad North American term for any motorized or towable vehicle designed for recreational travel and temporary living, including motorhomes, campervans, travel trailers, fifth wheels, and pop-up campers.

In Europe, the equivalent terms are "motorhome" (for self-propelled units) and "caravan" (for towable trailers). The global RV market is valued at over $50 billion annually.

A roof vent is a ventilation hatch installed in the motorhome or caravan roof to allow hot air to escape and fresh air to circulate. Most include an integrated fan for active ventilation or extraction.

Roof vents are essential for managing heat and moisture, preventing condensation and mould. Popular models include the Dometic Fan-Tastic, Remis, and Seitz hatches. They are usually 400 × 400 mm and fit standard roof openings.

A satellite dish is a parabolic antenna mounted on a motorhome roof or set up on a tripod that receives broadcast satellite TV signals (Astra, Hotbird) or connects to satellite internet services.

Motorhome satellite systems range from simple fold-flat panels to fully automatic roof-mounted domes that self-align when parked. Popular brands include Selfsat, Oyster, and MAS. Reception requires a clear view of the southern sky in Europe.

A semi-integrated motorhome is built on a van chassis (typically Fiat Ducato or Mercedes Sprinter) in which the driver's cab is retained with its original dashboard, but a separate coachbuilt body is fitted behind it.

Semi-integrated models are lighter and more affordable than fully integrated motorhomes. They are the most popular motorhome type in Europe, offering a good balance of comfort and drivability.

Shore power is mains electricity (230V AC in Europe, 120V in North America) supplied to a motorhome or caravan via a cable connection to a campsite power post, allowing 230V appliances and battery charging.

"Shore power" terminology is borrowed from marine usage. The standard European campsite socket is a 16A CEE 17 (blue commando) plug. Hook-up points typically provide 6A, 10A, or 16A depending on the campsite.

A slide-out is a section of a motorhome's wall and floor that slides outward hydraulically or electrically when parked, extending the interior living space by 20–40 cm on one or more sides.

Slide-outs significantly increase interior width when parked but must be fully retracted before driving. Multiple slide-outs are possible on large Class A motorhomes. They require regular maintenance of seals and slide mechanisms.

A solar panel is a photovoltaic panel fitted to a motorhome or caravan roof that converts sunlight into 12–24V DC electricity to charge leisure batteries and power 12V appliances directly.

A 200W panel in summer sun produces approximately 80–100Ah per day. Most systems include an MPPT (Maximum Power Point Tracking) solar charge controller for maximum efficiency. Panels are rated at 25°C under STC conditions.

Starlink for RVs is SpaceX's satellite internet service configured for mobile use, providing broadband internet (50–250 Mbps) to motorhomes, campervans, and caravans from low-Earth orbit satellites.

The Starlink "Roam" plan allows use in any country where the service is available. The flat rectangular dish (about 30 × 50 cm) requires a clear view of the sky and draws around 50–75W during operation. Available in most of Europe, North America, and Australia.

Stellplatz is a German term for a dedicated motorhome parking pitch, either standalone or part of a Wohnmobilpark, typically with electrical hook-up, fresh water, and grey water disposal.

Germany has over 2,500 official Stellplätze. Many are located at tourist attractions, town centres, or wine estates. The ADAC app and Stellplatz.de directory list most locations. Prices range from free to €25 per night.

Truma is a German manufacturer and the leading brand for motorhome and caravan heating systems, water heaters, gas pressure regulators, and air conditioning, fitted as standard by most European motorhome brands.

Truma's product range includes the Combi combination heater-boiler, the S series blown-air gas heaters, the Vario electric boiler, the Aventa air conditioning, and the DuoControl gas switching system. Based in Putzbrunn, Germany.

The Truma Boiler (now called Truma Vario) is a compact gas and/or electric hot water heater for motorhomes and caravans, heating a 10–14 litre tank of water for showers and washing without requiring an on-demand system.

The Boiler E model runs on 230V electric only; the Boiler B on gas only; the Boiler EB on both. Recovery time from cold on gas is approximately 20–30 minutes. The Vario range adds connectivity for app control.

The Truma Combi is a combination gas and electric heating system that provides both space heating (blown air via ducts) and hot water (10-litre boiler) in a single compact unit, the most popular heating solution in European motorhomes.

The Combi 4 (4kW) suits campervans and smaller motorhomes; Combi 6 (6kW) handles larger vehicles. "E" suffix means it can also run on 230V electric heating element. The TrumaNet/Truma App allows remote control and monitoring.

The Truma DuoControl is an automatic gas pressure switching system that connects two gas cylinders and automatically switches to the full cylinder when the first one runs empty, without interrupting the gas supply.

Eliminates the inconvenience of running out of gas mid-journey or overnight. The DuoControl CS version adds crash sensor technology that shuts off gas supply automatically in the event of a collision. Standard on many factory motorhomes.

A van conversion is a standard cargo van, minibus, or panel van that has been converted into a campervan or motorhome, either professionally or as a self-build project.

Popular base vehicles include the Mercedes Sprinter, VW Crafter, Ford Transit, and Renault Master. Unlike factory campervans, conversions vary widely in design and quality and are not subject to M1-class type approval.

Van life is a lifestyle in which people live and travel full-time or part-time in a converted van, campervan, motorhome, or similar vehicle, using it as their primary home.

Van lifers typically convert cargo vans or campervans into living spaces with a bed, kitchen, and storage. The lifestyle is popular in Europe and North America, driven by remote work, minimalism, and a desire to travel freely without fixed accommodation costs.

The VanBasket Index is a food and essential goods price index developed by OpenVan.camp to help van lifers and motorhome travelers compare living costs across countries. A score of 100 equals the world average.

The index is based on the World Bank International Comparison Program (ICP) 2021 baseline, adjusted monthly using IMF Consumer Price Index data. Countries with a VanBasket score below 70 are considered budget-friendly; above 130 are expensive.

The VanSky Score is a 0–100 weather and climate suitability index developed by OpenVan.camp, measuring how comfortable conditions are for van life and motorhome travel in a given location and time of year.

The score combines temperature comfort (35%), solar energy availability (25%), rainfall (25%), and wind conditions (15%), based on real-time data from Open-Meteo. A score of 80–100 is ideal; 0–19 is considered unbearable.
