When the warm and moist air inside the van comes in contact with any smooth and cold surface, such as windows, it immediately forms into a water vapor or condensation.
Taking the given points into consideration, you need to control a few things to stop or at least minimise the condensation in your van.
Excellent campervan ventilation and airflow are the best ways to stop condensation and the only way to effectively win the battle.
If you’re serious about stopping condensation in your van, you’ll install one or two electric roof vents.
Opening a window in the van is an easy solution.Our windows are almost permanently open when we’re in it, even with 3 roof vents.
Adding a portable 12v fan to your condensation fighting arsenal can help too.
Given moisture in the van is the source of condensation issues, controlling how much water vapor you produce makes the fight easier.
Burning propane produces a LOT of water vapor – about 1 pint of water for every pint of fuel burnt!
