Lowes sells it. all the small pieces of stone are fixed to a 12x12 screen.
The stock wall board has a wall paper .
Has anyone used a product called simple mat for prep?
Like this?

There is considerable amount of weight in the stone plus grout..
I wouldn't directly attach that to existing RV wall board unless you really like putting the stone back up often.. RV wall board is thin, not supported well, flexes quit a bit and not to mention the surface is nothing more than a sheet of paper glued to the wall board..
The job is only as good as the weakest point which most likely will be the paper on the wall board tearing away..
