As the leaves start turning and that autumn chill creeps in, many VW camper owners start thinking about winter storage. While some hardy souls use their vans year-round (and fair play to them), most find the combination of cold weather, road salt, and reduced camping opportunities makes winter a natural time to give their beloved bus a rest.
Done properly, winter storage isn’t just about parking up until spring – it’s an investment in your van’s longevity and your future adventures.
Indoor vs Outdoor Storage
Indoor Storage: The gold standard, but not always practical or affordable. A heated garage prevents condensation issues and protects paintwork from UV damage and the elements. Expect to pay £50-80 per month for secure indoor storage around Worcestershire.
Outdoor Storage: Perfectly acceptable with the right preparation. Choose a level, well-drained surface away from trees (falling branches and bird mess). A breathable cover designed for camper vans will protect paintwork while allowing moisture to escape.
Your Driveway: Often the most practical option. Use a quality cover and check on your van regularly. Avoid parking under trees or where ice might form around the tyres.
Pre-Storage Preparation
Mechanical Preparation
Change the Oil: Old oil contains acids and contaminants that can cause corrosion during extended storage. Use quality oil and replace the filter too – it’s cheap insurance.
Top Up the Tank: A full fuel tank prevents condensation and reduces the risk of fuel system problems. Add a quality fuel stabiliser to prevent the diesel from degrading.
Check Coolant: Ensure your antifreeze is up to scratch. A 50/50 mix should protect down to -37°C, more than adequate for British winters.
Tyres: Inflate to maximum recommended pressure (check the door pillar sticker). Consider tyre cradles or moving the van monthly to prevent flat spots developing.
Battery Care: Disconnect the main battery and connect to a quality smart charger or battery conditioner. Don’t forget the leisure battery – these expensive units hate being left flat.
Interior Preparation
Deep Clean: Remove all food, crumbs, and organic matter. Mice love setting up winter homes in warm camper vans, and leftover food provides an open invitation.
Ventilation: Leave roof vents slightly open and interior doors ajar. Good air circulation prevents condensation and mildew. Remove soft furnishings if possible, or at least ensure they’re completely dry.
Moisture Absorption: Moisture traps or dehumidifiers help maintain a dry interior. Those disposable moisture absorbers from hardware shops work brilliantly and cost pennies.
Gas Systems: Turn off gas at the bottle and run appliances until the lines are empty. This prevents any leaks during storage and is simply good practice.
Water Systems
This is where many owners get caught out. Water system damage from freezing can cost thousands to repair properly.
Drain Everything: Fresh water tank, pipes, water heater, and waste tanks. Don’t forget the water pump – these can crack if water freezes inside.
Blow Out Lines: Use compressed air to clear water from all pipework. Pay particular attention to low points where water might gather.
Antifreeze Option: Some owners prefer adding RV antifreeze to their systems rather than draining completely. This works well but requires specific non-toxic antifreeze designed for drinking water systems.
Monthly Health Checks
Even stored vans need attention. Monthly checks prevent small issues becoming expensive problems:
Start the Engine: Run for 15-20 minutes to circulate fluids and charge the battery. Don’t just idle – take it for a short drive if possible.
Check for Leaks: Water ingress is your van’s biggest enemy. Look for damp patches, condensation, or musty smells.
Pest Inspection: Look for signs of mouse activity – droppings, chewed materials, or nesting. Act quickly if you find evidence.
Tyre Pressure: Check monthly and adjust as needed. Consider moving the van slightly to prevent flat spots.
Spring Awakening
Come March or April, your van needs proper recommissioning, not just a quick start and go:
Fluid Checks: Oil, coolant, brake fluid, and power steering fluid should all be checked and topped up as needed.
Water System Flush: Flush through with fresh water several times before first use. Run hot water to ensure the heater’s working properly.
Safety Systems: Test smoke and gas detectors, and ensure your gas system’s working correctly before that first camping trip.
