Caulking & Spray Foam

thanks for the quick reply! from what I've seen/read, the newer spray foam cures in 60 seconds - two minutes. mainly, the entire frame is done with 1 1/2" x 1 1/2" beams, so for the most part I could only go over it once but the floor and roof are different, also the bed over cab. I haven't bought anything yet, but the situation here is - time is critical. I can't have this here for much longer, it needs to be moveable is less than two weeks. she runs, but is currently a flatbed truck. I have one friend building the frame while I slave over this caulking, lol...
