Had to remove the remaining interior aluminum skin to get at 25 years of rotten insulation and general putridity. Some pieces were already removed/destroyed and the remainders were used to patch the belly pan and other invisible locales. I am planning to hang thin higher grade plywood on the interior walls.
I have seen a handful of threads with wooden walls but can't seem to find a good description of how best to hang the plywood. Remember, I don't have the interior aluminum to attach wood to. I'm assuming that I will need to fill the channels in the walls with pieces of wood for the screws to "bite" into and that I will need to score each individual piece.
Any thoughts on how best to undertake this process would be appreciated. It's gonna be "fun"!
