Winter camping: gas, air and water in a motorhome in frost

The German motoring club ADAC and the publication promobil have issued guidance on operating motorhomes in winter. According to ADAC, an 11-kilogram gas cylinder lasts about two to three days in winter, while consumption at minus 10 degrees Celsius can reach around five kilograms per day. A week at that temperature requires about 35 kilograms of gas, or more than three cylinders. ADAC lists a two-cylinder system with automatic changeover as basic equipment and advises using winter gas, which remains gaseous at sub-zero temperatures. To remove condensation, the interior should be ventilated with windows and doors open for five minutes at least twice a day. Forced ventilation must remain open to protect against carbon monoxide, and the heater's intake and exhaust openings must not be covered by snow. If the waste water tank is not insulated and heated, the drain valve should be left open with a bucket underneath.
