I have been stymied for awhile on how to attach my interior walls to the exterior skin of the truck. Much like backyard burgers van my truck has nothing but smooth 1/8 aluminum walls.
My ordinal plan was to run 3/4 plywood strips on the walls for studs and attach 1/2 plywood over that. I’d go with thicker walls but my press will just barely fit as is and the is no room for anything more. I am planning to bolt the studs on through the exterior skin and I’ll seal the holes with a marine/ rv grade sealant. Not excited about drilling adding holes but seems like it has to happen.
There has to be some sort of frame or stiffener to support the outer skin. Flat sheets want work otherwise.
