Condensation

Having problems with condensation in the back of my van, what’s the best way to stop this

You need to either make the air inside the van less damp, or prevent the damp air from coming into contact with cold surfaces (i.e. metal).  The former might not be feasible if, like me, you tend to carry damp or living cargo, so the alternative would be to experiment with insulating the (metal) surfaces that the water condenses onto.

I fitted adhesive backed foam rubber to the interior roof of my van, worked great. Also makes it a lot quieter and removes the boomy sound. Easy to get on eBay by the roll. Or use stretch carpeting.

Fit a rotating roof vent? Leave your aircon on all the time?
