Has anyone managed to find a roof vent fan which is more or less flush from the outside? Ideally no more than 2cm raise, 5cm max.
Looking for a powered fan, one at each end probably to create a tunnel effect.
Dont want to go over 2m total height for my van, so I can still get in my local supermarket car park!

big thread revival here, but I'm also wondering the same - don't want to add much height, but for temparature and moisture control surely this is a must?
