How to Store Your Camper Van for Winter
If your van spends the winter parked instead of out exploring, a little preparation now can save you from unexpected repairs when spring rolls around. Cold temperatures, moisture, and systems sitting unused can all create problems if your van isn't properly prepared for storage.
The good news? You don't need to do everything at once. A little maintenance before winter can go a long way toward protecting your investment and making sure your van is ready for your next adventure.
Here's what we'd check before putting a van away for the season.
1. Empty and Prepare Your Water System
Water is one of the biggest things to think about when temperatures drop. Water left in tanks, pipes, pumps, or other components can freeze, expand, and cause damage.
Before storing your van:
Empty and clean your fresh and gray water tanks.
Drain the water lines, pump, water heater, and other plumbing components according to the manufacturer's instructions.
Make sure water isn't trapped in low points or other parts of the system.
If your van has a more complex plumbing setup, follow the appropriate winterization procedure for each component.
Simply emptying the tanks may not be enough to protect your entire system. If your van will be exposed to freezing temperatures, take the time to winterize the plumbing properly.
2. Take Care of Your Batteries
Your battery system needs attention before winter storage, too. Cold temperatures can affect battery performance, and different battery chemistries have different storage requirements.
Check the battery manufacturer's recommendations for storage temperature, state of charge, and whether the battery should remain connected to a charging source. If your system includes a battery monitor, charger, or other connected components, make sure you understand how those settings affect storage.
If you have lithium batteries with low-temperature charging restrictions, pay particular attention to those requirements. Some batteries have built-in heaters or battery management systems, but those features don't replace the manufacturer's storage guidance.
Don't assume every battery should be left fully charged, disconnected, or on a trickle charger. The right approach depends on the battery and your specific setup.
3. Check Fuel and Your Heater
If your van has a fuel-powered heater, winter storage is a good time to give it some attention.
Change the heater filter if your model uses one and it's due for replacement.
Inspect the fuel supply and connections for any visible issues.
If your heater hasn't been run recently, operate it for at least 30 minutes according to the manufacturer's instructions, provided it's safe to do so.
Running the heater helps exercise the system and can help clear out old fuel in the line. It also gives you an opportunity to notice unusual sounds, error codes, or startup problems before you need heat on a cold night.
If your van will sit for an extended period, check the heater manufacturer's recommendations for long-term storage and maintenance.
4. Clean Your Solar Panels and Check Electrical Connections
Solar panels can collect dust, dirt, pollen, and other debris over time. Before winter storage, clean your panels according to the manufacturer's instructions so buildup doesn't sit on the surface for months.
While you're at it, take a look at accessible electrical connections.
Check for signs of corrosion, loose connections, damaged wiring, or anything that looks out of place. Don't pull apart live electrical connections or attempt repairs unless you know how to safely work on your system. If something looks questionable, have it inspected.
It's much easier to address a potential issue while you're preparing for storage than to discover it when you're ready to leave on a trip.
5. Inspect Exterior Seals and Roof Accessories
Water intrusion can cause expensive damage, and winter weather can make existing sealing problems worse.
Take a close look at the seals around roof penetrations and exterior accessories, including your Maxxair fan, solar panel mounts, vents, and other roof-mounted equipment.
Look for cracked or peeling sealant, gaps, lifting edges, or other signs that a seal may be failing. Address anything that needs resealing using materials compatible with the roof surface and the original installation.
If you're unsure which sealant to use or how to repair a particular penetration, it's worth getting professional advice. Using the wrong product can create more work down the road.
6. Don't Forget the Rest of the Vehicle
Your campervan is also a vehicle, so don't overlook the basics.
Check tire pressures, inspect your tires, and follow the vehicle manufacturer's recommendations for extended parking. Consider where you're storing the van, whether it's protected from the elements, and how you'll keep an eye on it throughout the winter.
If your van will be stored for several months, consult the owner's manual for guidance on the engine, fuel system, parking brake, and other vehicle-specific requirements.
Your Winter Van Storage Checklist
Before putting your van away, make sure you've covered the essentials:
Empty and clean the water tanks.
Properly winterize plumbing and water-using appliances.
Check battery storage requirements with the manufacturer.
Inspect fuel systems and follow applicable fuel-storage guidance.
Change the heater filter if due and run the heater as directed.
Clean solar panels.
Inspect accessible electrical connections.
Check exterior seals and reseal any areas that need attention.
Remove damp items and address interior moisture.
Check tires and follow vehicle storage recommendations.
A Little Maintenance Now Makes Spring Easier
Winter storage is a great opportunity to take care of the maintenance that can get overlooked during a busy season of adventures. A few checks now can help you catch small issues before they turn into bigger problems.
And if you're not sure how to winterize a particular system or something doesn't look right, don't guess. Every van setup is a little different, and the right approach depends on the equipment you have installed.
We're here to help you understand your setup, maintain your systems, and keep your van working the way you need it to. A little preparation now means fewer surprises when it's time to get back out there.
