You probably have linoleum then plywood under your carpet. The way I understand it when they build these things they add plywood to the frame then lay the linoleum on top of the plywood then carpet over that. The carpet is then cut to expose the linoleum wherethe linoleumshould show.
my son says plywoor, but if I remember right, I have seen linoleum under carpet in my other rv
tks
Not all of the carpet will have lino under it, much depends on the floor plan and where the exposed lino is located. Also, there will be hundreds of carpet staples thru the lino making it unsuitable as an exposed, final flooring.
