A camper van is a small box surrounded by prairie cold. Whether you are storing it for winter or living in it, three issues matter most: water, moisture and power.
Protect the water system
If the van will sit through freezing temperatures, drain tanks, lines and pumps fully. Use RV-safe antifreeze only in systems designed for it, and keep it out of anything you drink from.
Control condensation
Breathing, cooking and wet gear create moisture that condenses on cold surfaces. Ventilate a little even when it is cold, use a fan or vent, and keep insulation continuous so there are fewer cold spots.
Batteries and power
Cold reduces battery capacity, and lithium batteries often cannot charge below freezing without built-in protection. Check your manufacturer limits, insulate the battery bay, or remove the batteries for storage.
Heat safely
- Use heaters rated for enclosed spaces.
- Install a carbon monoxide alarm and test it.
- Never run unvented fuel heaters inside.
- Keep flammables clear of heat sources.
A winter checklist before you park the van
Empty the water system, remove food and anything that can freeze or attract rodents, clean the interior, and prop doors slightly if it will sit long term. Check tires, fluids and the battery before the first deep freeze.
If you live in the van through winter
Plan for propane or diesel heat that is properly vented, add window insulation, and expect to manage condensation every day. Know the limits of your power system, since solar output drops sharply in short, cloudy winter days.

Frequently Asked Questions
Do I need to drain my van water system for winter?
If it will be below freezing, yes. Frozen water can crack tanks, lines and pumps.
Why does my van get so much condensation in winter?
Warm, moist indoor air meets cold metal surfaces. Ventilation, insulation and moisture control reduce it.
Can lithium batteries freeze?
They should not be charged below freezing unless the battery has low-temperature protection. Check your manufacturer’s specs.
