Which motorhomes and camper vans are suitable for winter?

A lot of the manufacturers of motorhomes and campervans based in Europe have recognized the trend towards winter camping and have been offering appropriately equipped vehicles for many years. This applies, for example, to all motorhomes and camper vans from the Erwin Hymer Group brands, all of which have been winter-proofed and thus are suitable for winter camping. You can be sure of this, because product development for all these brands includes an extensive endurance test in the cold chamber and subsequent optimization of the vehicles for the special conditions in the cold season. During the test in the cold chamber, the interior of the vehicle is cooled down to at least 0°C over several hours. The heating must then be able to reach an internal temperature of 20°C within two hours. An infrastructure that has been thoroughly checked in this way is essential on a winter holiday, since it might be noted as annoying if the heating does not work properly in spring or autumn. In winter it would mean that the holiday very suddenly is at an end.

Motorhomes and camper vans that may be definded as winterised go one step further: For winter-proofed motorhomes only the heating behavior is measured. For winterised motorhomes, however, the stabilization time or insulation as well as the water system are also examined carefully. In addition, a winterised vehicle must be able to withstand significantly lower temperatures. For this test, the motorhomes are cooled down to -15°C for at least ten hours. The heating system then has to be able to heat the interior to 20°C within four hours. In addition, it is checked whether the vehicle can keep this temperature over a longer period and whether all water pipes and systems function properly even in the cold and do not freeze.

Should only vehicles from the premium segment be considered for winter camping?

All motorhomes and camper vans that pass the test for winter-proofed vehicles are also suitable for winter camping. As mentioned above, this applies to all motorhomes and camper vans from the Erwin Hymer Group brands - regardless of the price range. In the Sunlight models in the entry-level category, for example, the built-in Styrodur material ensures solid insulation in both the motorhomes and the campervans. These models are particularly popular with younger winter sports enthusiasts, especially since they weigh less than 3.5 tons and can be driven with a class B driving license. Those who wish for even more comfort in winter can also expand the basic equipment of these models, for example with an insulated and heated waste water tank or a more powerful heating system. Many manufacturers such as Dethleffs, Bürstner or LMC also offer special winter packages for vehicle configuration, which often include underfloor heating.

Naturally, the higher the price category, the higher the comfort and the insulation properties, which also reduces the gas consumption of the heating system. The Hymer brand, for example, achieves outstanding insulation properties with its side walls made of patented PUAL foam: “The insulation of this closed-pore PU foam is comparable to that of an 80 centimeter thick solid brick wall,” says Dominik Hepe, Product Manager Motorhome at the Erwin Hymer Group. This also helps to ensure that all current Hymer motorhome models are winterised even with the basic equipment ex works. In the premium segment, the vehicles are also equipped as standard with a heated double floor with a temperature-controlled shower tray and high-quality framed windows with double acrylic glazing. In the models of the higher classes such as the Hymermobil Masterline or ModernComfort, the fresh water tanks and waste water tanks are also located in the insulated double floor of the SLC chassis, through which warm air flows so that objects in the chassis cannot freeze. This also applies to the batteries, which of course has a positive effect on their service life.

From model year 2023, all Fiat-based Hymer campervans are also winterised as standard. Optional winter extras can be selected for all other Hymer campervans.

What else should you look out for in vehicles for winter camping?

Not only does the right heating system play an important role in winter camping, but also the right air circulation. Because only an ingenious air circulation and rear-ventilated overhead storage cupboards prevent the formation of condensation and ensure a comfortable room climate. This is why, for example, all motorhomes from the manufacturer Dethleffs come with the company's own AirPlus ventilation system and hot water heating as standard. Motorhomes from the Dethleffs models Esprit, Alpa, Globetrotter XL I and Globetrotter XXL A are also winterised as standard.

In addition, the correct heat distribution in the entire motorhome must be guaranteed. "The brands of the Erwin Hymer Group make sure that the bathroom can be heated very well," emphasizes product manager Dominik Hepe. As a snowboarder, he likes to camp in winter himself - preferably somewhere in the great outdoors. “If you are self-sufficient, you can even use the shower as a drying room for ski clothes. In the case of higher vehicle classes, the heated rear garage is also an ideal solution." However, it is also important that the moist air can leave the vehicle.

Worthwhile accessories for winter camping

Especially when it comes to keeping an eye on the gas supply, every winter camper should have a level measuring device in their luggage. These are available in various forms and in various price ranges in different camping accessories shops.

In addition, when camping in winter, one shouldn't ignore the largest cold bridging source in the vehicle: the windshield. For example, Hymer has developed a so-called warm air curtain for its fully-integrated motorhomes, which can be optionally ordered when purchasing the vehicle and which contributes to the optimal climate. The dashboard is heated even when you are at home and an electric roller shutter prevents the heat from escaping through the panoramic windscreen. For everyone else, it is worth buying special insulation mats that can be placed on the windshield either from the outside or from the inside. These are available from the accessories trade or from the original accessories shops of the individual vehicle manufacturers. In the camper vans segment, for example, Carado offers thermal insulation for the windscreen and rear doors. Dominik Hepe reveals another trick: "Tinkerers often get a styrofoam board from the hardware store, cut it to size and place it in the window from the inside." In all vehicles, the room climate can also be made even more comfortable with custom-made carpets for the living area.
