If you store your motorhome safely over the winter, you not only protect the technology, but also your health and your own budget. Proper storage ensures that the water, indoor and outdoor systems survive the winter undamaged and the motorhome is ready for use again in the spring.
Drain the water system
The water system is one of the most sensitive areas of a motorhome. Even small residual amounts in pipes, pumps or fittings can lead to expensive damage in the event of frost. That’s why winter preparation begins with thorough cleaning: limescale, biofilm and organic residues in the fresh water tank and the pipes should be removed before winter operation, as the online magazine Promobil explains.
Then you have to open all the taps, activate the drain valves and frost monitors, shake out the shower hose and flush the toilet several times. TÜV NORD also recommends completely emptying the waste water tank and adding some antifreeze to unheated vehicles to prevent freezing.
Prepare the interior
Careful preparation is also required for the interior. It protects against moisture, unpleasant odors and loss of value. According to camping retailer Fritz Berger, all food and moisture-sensitive items should be removed. The refrigerator and storage compartments should also remain open. Cushions should be put up so that the air can circulate better.
It is also advisable to disconnect the battery or leave it connected via a trickle charger. Electronic devices should be outsourced. To avoid waterlogging, it is advisable to keep doors, windows and roof hatches slightly open.
Check the outer shell and technology
Caring for the outer shell plays a central role in maintaining long-term value. Exterior walls, underbody and wheel arches should be thoroughly cleaned and checked for damage. Seals and awnings also need care so that they remain supple. TÜV NORD also recommends checking tire pressure as well as engine, brake and coolant regularly. If you park the vehicle for a long period of time, you should move it occasionally. This way you can avoid flat spots and stuck brakes.
Location selection and battery usage
Where the motorhome spends the winter has a major influence on its condition. A covered or sheltered parking space offers the best protection from frost and moisture. According to TÜV NORD, special attention should be paid to the batteries: starter and on-board batteries should be connected to shore power or charged regularly using a trickle charger. This means they remain fully functional even after several months and are not damaged by deep discharge.
Financial perspective
Good winter preparation pays off financially. If you care for your motorhome carefully, you significantly reduce the risk of expensive repairs due to frost or corrosion. In addition, the resale value of a well-preserved vehicle remains significantly higher. As TÜV NORD emphasizes, the condition after the winter break can be crucial for potential buyers. Anyone who invests in care and storage in good time not only protects technology and equipment, but also their own budget in the long term.
