Structure and panel questions 99 38b Monaco diplomat

I am looking at a 99 Monaco diplomat the rear bedroom has been stripped tithe aluminum studs. The rear wall the studs have been cut out. Is there a place I can get some pictures of how it was framed. Alsoin the exterior walks the Fiberglasd panel is attached to a 1/8 inch looks like mahongony panel when they build the coach how do they attach these panels to the aluminum structure, they are not screwed. So I am guessing pl premium or sicoflex . There apparently there is 1/4 foam panels, then the wall panels. Anyone know of some pictures exposed view drawings.
