Yep, that's sounds like the rear end on my 69 ambassador. That spray foam was really nasty.. It burns your eyes and get every where when you scrap it off. Plus it burns fast.. I don't know if the new spray foams have better moisture resistance. Letting the inside of the frame breath is probably a better idea.

Yikes. As much as I loathed the moldy, itchy fiberglass removal from our trailer, it sounds like it would have been much worse if we'd had spray foam to deal with. I think we'll play it safe and not use any foam, and just use mesh and a metal cap on one end to keep the critters and creepy crawlies out. Will post pics when finished.
