That's a big concern- especially for camper vans. Ventilation is key, and several people sleeping inside, or cooking, esp. with LPG gives off lots of water vapor. I did use the reflective bubble foil directly against the wall, hoping for a type of vapor barrier, but I could the benefit of a home-style vapor barrier on the interior wall. I did read somewhere that sportsmobile uses denim insulation.

So are you saying the interior of a Sprinter is rust prone as well?
