All, for what it’s worth, when I removed the inner skin on Argo, I found the spray-in foam dry and in decent condition. I stripped all the old foam out to upgrade the insulation to polyisocyanurate, the highest R value material currently available, and to rewire the rig to a marine standard.
I found plenty of wet in the plywood - wet and rotten. The wet was because the nice fellow I bought Argo from had gone to great lengths to have the rig looking clean for my visit as a potential buyer. He’d taken it to a big truck wash and they had hosed it hard all over. This revealed lots of leaks!
My point is that the spray-in from the factory was well-done and dry.
Incidentally, I reinsulated by gluing 1/2” sheets of polyiso onto the inner skin, building up three layers. Then I sprayed Dow Froth-PAC polyurethane foam over the whole inner surface to seal things up. So far no leaks... if I were doing it again, I’d skip the polyiso sheets and just spray fresh foam to a 1 1/2” thickness. It’s a less daunting task than it seemed at the time.
