X2 with what dunnnc said. When I wanted to put a TV mount in the "master bedroom" on our Grey Wolf I took a piece of 1X6 and happen to have some stain that matched the cabinets pretty good. I just pre-drilled and counter sunk 4-2.5" screws (2 on each end
of the board) then mounted that to the wall, then mounted the swivel TV mount to that. It was quick and simple, also whenever we sell the camper it can be removed and there will only be 4 small 1/8" holes that can easily be filled.
