Thanks, @Titan . That is my line of thought as well. The only thing I can really find on U-ply is that it is used as flooring underlayment.Sounds like it’s just the thin wall coverings most trailers use. 1/4” paneling. I think mine has some 3/8” or so plywood. Still not really thick enough to mount anything to it. I always mount everything to the steel supports every 16”.
I probably wouldn’t pay anything extra to upgrade the walls, unless it was to make them waterproof. Plywood thick enough to actually use is almost a waste of weight capacity to me.
