How do you guys heat the rear area of your van? I have a renault trafic, with a fixed bulkhead, so the back is completely separate, and I find that in the winter it gets quite damp, condensation dripping from ceiling etc I'm embarassed to say but the other day I found some mushrooms growing in a corner... The front of the van heats up to boiling temperatures in about 10 mins of driving, so I was thinking about how I could divert the hot air towards the back. The bulkhead has a removable window thingy (which I heard is quite difficult to take out, but not impossible), do you think the hole would be big enough to make a difference in temperature in the back? (not my van, but that's the hole i'm on about) Or do you have any other methods to heat the back? I don't have a driveway so extension lead+220v heater is not an option.
