One thing you might try, on the cheap, is roofing emulsion and carpet
padding. Paint the emulsion on the inside of the body, then stick your
sound-deadening carpet padding right in it. These materials  will do the job
fairly well without spending a fortune. You can get the emulsion in silver
so the finished product looks somewhat professional, too.

Marcel Proust lined the inside of his apartment with cork for sound
deadening, but I doubt his walls had the contour of the Vanagon body. How
would you get these tiles to stick permanently to the body? My experience
with stick down tiles is they work pretty well with the help of gravity, but
on a car wall, given the heat and vibration, I bet they'd end up falling off
in no time. That adhesive doesn't amount to much.

If the paint you're using is latex, you might try to find out if it's going
to stand up to the hot sheet metal on a summer day. Maybe put some on a
piece of sheet metal, set your oven to 130 F, etc. House walls don't usually
get that hot. The roofing emulsion I'm talking about is made for aluminum
roofs on mobile homes and the like.
