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.
Previously owned a 1965 Overlander, fully renovated it, then sold it after a year of full-time travel. We're taking a break from trailers to try a class A for a while, but we're still Airstreamers at heart!
