Protecting your motorhome during the winter lay-up

Experienced motorhome owners will already understand these important aspects of ownership and have established routines for their vehicles, but a surprising number of owners still experience ‘post-hibernation’ issues. We hope this brief guide will help more motorhome owners have a safe and secure winter break.

Winter brings a natural pause for many motorhome owners. Once the trips are over and the temperatures drop, the vehicle often sits still for months. This quiet period is helpful but it can also expose your motorhome to damp, flat batteries, stale fuel, tyre damage, and interior wear.

Owners who prepare carefully tend to avoid these problems. The steps are simple, but each one protects a different part of the vehicle and helps preserve its value.

Keep it Clean

The first task is to give the motorhome a clean before it goes into storage. Sounds obvious but dirt, road salt, and tree sap left on the bodywork can trap moisture and encourage corrosion over time. A clean surface dries faster and is easier to check for any small scratches or chips that need attention. The interior deserves the same care. Food crumbs, damp coats, or forgotten toiletries can all lead to mould or unwelcome smells. A dry, tidy space stands up far better to long periods without use.

Keep it Dry

Attention then shifts to moisture control. As we’ve covered in recent articles, motorhomes are prone to condensation when the temperature swings between cold nights and mild days. Owners who place moisture absorbers inside the living space usually see a big difference. Curtains left slightly open help air to circulate. Any soft furnishings should be dry before storage because trapped dampness is one of the main causes of mould growth through winter.

Mechanical Care

Mechanical care follows. A healthy battery does not enjoy being ignored for months. Most owners either disconnect it or keep it topped up with a smart charger which supplies a gentle, steady charge. This prevents sulphation, a process where the plates degrade if the battery sits at a low charge. Fuel can also break down in time, so topping up the tank can reduce the amount of air inside and help limit condensation in the fuel system. Fresh oil before storage can also protect the engine because used oil holds acids that are not ideal during long lay-ups.

Don’t forget the Tyres

Tyres deserve attention too. A heavy motorhome left in one position can develop flat spots, especially in cold weather. Moving the vehicle slightly from time to time can help. Some owners raise tyre pressures a little within safe limits to reduce the strain on the sidewalls. It is also worth checking that the weight is spread evenly so the suspension does not settle awkwardly.

 Keep it Safe

Security is also part of the winter routine of course. A motorhome sitting quietly on a drive or in a storage yard can be a tempting target. Simple steps make a big difference. Owners should always lock windows, secure internal doors, and remove any valuables. Those with an alarm or tracker should check that the system is working before the lay-up begins.

The Importance of Water

Water systems need care as well. Left untouched, small amounts of water in pipes and tanks can freeze and split seals. Draining the system fully avoids this risk. Many owners run the taps briefly after draining to make sure any remaining water clears the bends and connectors. Waste tanks also need emptying so no residue is left behind to freeze during a sharp frost.

An Eye on the Outside

The exterior fittings should not be forgotten. Roof vents, awning brackets, seals, and hinges all react to cold weather. A quick check before storage can spot drying rubber or loose seals. A light application of silicone on rubber trims helps keep them supple and avoids cracking.

Once these jobs are done the motorhome is usually safe to rest through winter. These small steps preserve the interior, protect the mechanical systems, and help the vehicle hold its value.

Happy hibernation and here’s to a great year ahead on the road.
