I have read they make a poly spray foam that is fire retardant for use in enclosed areas were it would be difficult for someone to get out..the polyiso is some good stuff to use is what will be going around my refer unit do to it's fire rating..the only problem i see in using sheet foam is getting a tight seal..i had to use can foam on my bead board to tighten it up...my two cents..
I have not been able to find a poly spray formula that says it is fire retardent but I would certainly be interested in it. I have read that Bigfoot uses sheet foam in some campers but maybe used spray foam in the past. Bigfoot and S&S are two manufacturers I wouldn't mind copying.
with your unit sheet foam may work alright..i figure it has the studs more evenly space than mine.. the down side of building a camper that big in the space of one car garage using junk tools.. :B plus the round edges of the steel should make it easier to stuff into cavity and i will keep an eye out for the article about the foam
