TrailManor has a TV wall mount available ($60 plus tax and shipping) from their Tennessee parts department. It suspends from the bathroom wall to face out over the sink and dinette/front bed end and easily unmounts by lifting it off the wall to store the TV during travel.  We're anxious to try ours next week at the South Carolina multi-forum rally but will pad it with some foam rubber to prevent rubbing the wall while at camp and causing vibrations while in the camper with normal walking in and about.
