Need to think about dew point, RH and differential temp. and have adequate thickness. You may need to drill/cut some small holes for access in some places. I would most definitely hire a pro for this. It tends to be very expensive partly due to setup and cleanup time - maybe you could tag onto the tail end of a building construction job if you drive the van to a site?? It might be that spray foam in a can is the way to go to get into small voids. If heat is a concern, would it be possible to drape sheets on the exterior and wet them?
