Knott has tested aerodynamic underbody paneling for travel trailers. The tests showed a 15% reduction in drag force, which theoretically lowers the tow vehicle's fuel consumption. The patented system could become available for series production and retrofitting existing caravans.

Mecklenburg-Vorpommern 91New camper registrations in South Korea fell 81% after the Kia PV5 arrived. Also: 1,000 illegal campers on Bulgaria's Karadere beach.
Two years on the road with a cat named Zhuzu — and not a single day of wanting to go back. We break down life in a camper van: where to find water, how heating works, what to do about electricity, and where to look for overnight spots. 7 countries, hundreds of places, and an honest account — from the mountain roads of Turkey to the coastline of Montenegro.
Comprehensive review of all RV and camper toilet types: cassette, portable, gravity, vacuum, macerating, dry flush, sealing, incinerating, composting and separating. Comparison of models, consumables, installation and annual costs.
The company Knott has developed a modular underbody panel for caravans to reduce aerodynamic drag. Tests with a Hobby trailer and a Skoda car showed a reduction in required traction force of 250 Newtons at 100 km/h. The plastic prototype weighs about 25 kg and can be installed by one person.
Tests revealed that a larger and heavier Fendt Bianco caravan consumes less energy than a compact and light Next 380 when towed by the same vehicle. Aerodynamics proved to be the key factor: the caravan's shape impacts fuel consumption and range more than its mass, especially at speeds around 100 km/h. The tests were conducted at the Bosch proving ground in Boxberg using a Tesla Model Y electric car and a diesel Skoda Karoq.
The Dethleffs C.Fold foldable caravan prototype was presented at the CMT 2026 show. The model weighs 775 kg, folds down to 1.65 m in height, and features an electric drive to raise the body. The aluminum composite construction and suspension system are designed to reduce aerodynamic drag when towed by an electric vehicle.
At the CARAVAN SALON in Düsseldorf, Westfalia will present the new Columbus Liner camper van based on the Fiat Ducato with a three-level layout. The model features a King Size bed, an optional Sky Lounge roof terrace, and a large rear storage compartment. Three diesel engines with 140, 160, and 180 hp are available, with prices starting at €84,605.

The vehicle is 1.99 m high and offers up to six seats.
On the morning of August 9, 2026, on the A3 near Seligenstadt, an 81-year-old driver of a VW Golf veered off his lane for unknown reasons and collided with a motorhome, causing his car to overturn and land on its roof. The driver was resuscitated at the scene and taken to a hospital, while his 74-year-old passenger sustained minor injuries. The motorhome was destroyed in the collision, leaving a large debris field on the road. Traffic towards Frankfurt was fully closed and partially reopened by 12:45 p.m. Damage is estimated at around 40,000 euros.
Hymer has unveiled the Eriba Touring 2026 lineup, combining retro design with modern amenities. The caravans feature compact dimensions, an aerodynamic body, and a pop-up roof that enhances fuel efficiency.
