We have fiberglass with foam bonded to the glass with plywood ribs and then plywood on top of that.
With all the experience I have in construction - I tried to visualize it.
NOPE, no clue.
Just picture a sheet of fiberglass topped with a 1" sheet of foam topped with a ~1/8" (or 3/16?) sheet of plywood. |III|. At least that's what I see in the basement near the gray water tank. I can't see the ribs, but the ribs would help explain how some things are screwed into the walls with strength.
In some rare cases with older NLs, I have seen discussion of the layers de-laminating, and loss of structural strength, typically where the cab-over meets with the rest of the camper.
