Has anyone used expanding foam insulation to replace the factory insulation? I've removed the aluminum and insulation under my Caravel
. I found a host of problems, from wiring that had been chewed through to a poorly constructed frame. I've fixed everything but I'm thinking expanding foam would be an excellent deterrent to keep rodants out. I was also thinking it could firm up the walls making the entire trailer less prone to dents, etc.
I had heard this type of foam could crubble, but I've not been able to find any confirmation to that.
