Winter camping is no longer a niche: outdoor enthusiasts and van life fans appreciate the freedom to travel flexibly even in the cold season. Skiers, snowboarders, and ski tourers also like to use winter camping as a flexible base station. With the right equipment and a winter-proof vehicle, there's nothing stopping your snow adventure. The TCS test shows that not only a strong heater is crucial, but the interplay of insulation, technology, and careful preparation.
Winter-Ready versus Winter-Proof
Cold, snow, and frost impose high demands on vehicles and equipment. Those traveling in winter should know what winter suitability and winter readiness really mean. According to the European standard EN 1646-1, a vehicle is considered winter-proof if it can be heated from -15 degrees Celsius outside temperature to +20 degrees Celsius within four hours, and the water system functions without restrictions thereafter. A vehicle is termed winter-ready if it still provides a comfortable interior at zero degrees, but without guarantees for frost-free water pipes. After an hour of stabilization time, the water system must also be filled and function without problems thereafter.
TCS conducted the test at 1,860 meters altitude at the Morteratsch campsite in Pontresina in the Engadin with a Frankia NEO MT7 BD Black Line. At temperatures between -7 and -18 degrees Celsius, the winter suitability and winter readiness were tested over several days. The heating performance, temperature distribution, energy efficiency, and operational safety of the water system were tested.
Technology, Insulation and Heating
Whether a motorhome is suitable for winter use depends significantly on three factors. Good thermal insulation is crucial. Vehicles with heated double floors and insulated tanks prevent important lines from freezing. Gas or diesel heaters with circulating air function provide an even heat distribution. An automatic gas switchover (two 11-kg bottles) increases operational safety. The third aspect concerns the water and energy supply. Frost protection for waste water tanks, a reliable power supply, and regular battery checks are essential.
TCS additionally recommends to avoid condensation by regular shock ventilation and to dry wet clothing outside the living area. Keeping the ventilation slots and the heater outlet clear is also crucial for the safety and efficiency of the system.
The general rule is: If you don't want to miss out on mobility and nature-based holidays in the snow, you should invest in a robust motorhome.
TCS Tips
- Tyres and driving: Winter tyres are mandatory - snow chains may be necessary depending on the destination.
- Vehicle protection: Rubber care sticks prevent frozen doors; an ice scraper and a shovel should always be on board.
- Gas and energy: Two gas bottles usually last five days with continuous use; electric heating cartridges can significantly reduce gas consumption.
- Ventilation and moisture: Open all windows for a few minutes two to three times a day to remove moisture and prevent mould.
