I've had a VW caravelle for 5 years and I'm only just planning my first stay in it 
I have got some thermal blinds on the way and my children are about to go on holiday with my exh for a week so next weekend I'm going to do a little trial locally.
I've camped in a normal tent often but never in such a small environment as a "camper van" (I know a caravelle isn't exactly a camper as the only campy things are the bed and a v small table, but you know what I mean!)
Any hints or tips?
