Winter transforms your van life experience into something completely different. Gone are the summer evenings with doors wide open and minimal gear. Cold weather requires preparation, smart solutions, and clever hacks to keep you comfortable on the road.
You might assume winterization means expensive upgrades and complex installations. The truth is that most effective winter preparations involve simple adjustments and strategic planning. These tips and tricks for winterizing your camper van will help you stay warm, dry, and happy during the colder months.
Why You Should Winterize Your Van
What's the big deal about winterizing anyway? Cold temperatures can cause serious damage. Water left in your pipes can freeze, expand, and then burst. This leads to expensive repairs that could have been avoided.
A van that is not winterized can also develop moisture problems. Condensation builds inside, which can lead to mold and mildew. These issues affect both your health and the structural integrity of your van's interior. A little prep work now saves a lot of trouble later.
Tip 1: Drain Your Water Systems
The most critical step is to drain all water from your van. This includes your freshwater tank, gray water tank, and black water tank. Frozen water expands, and that expansion can crack tanks and pipes.
How To Drain Your Tanks
Start with the freshwater tank. Open the drain valve, which is usually located at the lowest point of the tank. Next, open all your faucets, both hot and cold, to let air in and help the water flow out. Don't forget the shower and any outdoor faucets. Once the tanks are empty, close the faucets and drain valves.
Tip 2: Use Non-Toxic Antifreeze
Even after you drain the tanks, some water can remain in the lines and P-traps. To protect these, you'll want to add a non-toxic RV/marine antifreeze to your plumbing system. It's specifically designed for this purpose and is safe for your pipes.
Pump the antifreeze through the system until you see the pink fluid come out of each faucet. This confirms the lines are protected. Pour a small amount directly into your sink and shower drains to fill the P-traps.
Tip 3: Protect the Exterior

Winter weather can be harsh on your van's exterior, so it's important to prepare it for storage. Start by giving your camper van a thorough wash and wax. The wax will create a protective layer against snow, ice, and road salt.
While you're at it, check the undercarriage for any existing rust or damage. Applying a rust-proofing spray to exposed metal components is another great way to defend against corrosive winter conditions.
Inspect the seals around your windows, doors, and vents carefully. Look for areas where the sealant may have worn away. If you notice any issues, take the time to reseal them properly to keep water from sneaking in. Even small leaks can lead to water damage, especially during the wet and cold winter months.
By sealing these areas, you’ll protect your home from potential damage and improve energy efficiency with better ventilation.
Tip 4: Maintain Your Engine and Battery
Your van's engine also needs attention. Top off all fluids, including coolant and windshield washer fluid. An oil change before storage is also a good idea. Old oil contains contaminants that can damage your engine over time.
Consider a battery tender if you're storing the van for a long time. The cold can drain a battery, and a tender will keep it charged and ready for your first spring trip. This simple device can extend the life of your battery.
Tip 5: Keep Pests Out
To mice and other pests, a stored van looks like a five-star hotel. They'll sneak in to escape the cold, and once they do, they can cause some substantial damage. Chewed wires and upholstery? That's a nightmare to fix.
Remove all the trash from your van. Clean the interior thoroughly to remove any crumbs. Place pest deterrents, such as peppermint oil or steel wool, in any small openings to block entry points.
For extra protection, install a Ford Transit mosquito net to keep bugs and small critters from sneaking in through open doors or windows. It’s an easy and effective way to prevent unwanted guests while still allowing ventilation.
Tip 6: Use Insulated Curtains
Insulated curtains are a great addition for both active winter camping and storage. During storage, they add a layer of protection against the cold. They help regulate the interior temperature and reduce condensation.

Tip 7: Manage Interior Moisture
Ventilation is your best friend when it comes to moisture control. Even when your van is stored, air needs to circulate. Crack a window or a roof vent slightly to allow airflow.
You can also use moisture absorbers, like silica gel packs or commercial dehumidifiers. Place them throughout the van to collect excess moisture from the air. This helps prevent the growth of mold and mildew.
Tip 8: Service Your Tires

Tire care is another element to consider. Cold weather can cause tire pressure to drop. Before you store your van, inflate the tires to the manufacturer's recommended pressure.
If your van is stationary for months, the tires can develop flat spots. To prevent this, you can put the van on jack stands to take the weight off the tires. This small step helps preserve their shape and extend their lifespan. You wouldn't want to start your spring adventure with bumpy rides.
Tip 9: Get Your Paperwork in Order
This might not seem like a winterization tip, but it's an essential part of your preparation. Make sure your registration and insurance are up to date. Review your insurance policy to see what it covers during storage.
Some policies have different terms for when the vehicle is not in use. A quick call to your insurance agent can clarify any questions. It's better to be prepared.
Whether you’re gearing up for snowy getaways or tucking your camper van in until spring, these winterizing tips and tricks will keep your vehicle protected and ready for adventure.
