I mounted a 40" on a swing arm in our MH. I mounted 2 cabinet pull handles on either side of TV up close to the top. Went to hardware store and bought 2" wide nylon strap and locking buckles. Loop strap through handles pull tight with adjustable buckles. I also put a second strap around the lower part of the screen. On the cabinet behind the TV I mounted 2 swim noodles so that when the TV is pulled tight it helps cushion and hold it in place. I used 2 straps because I didn't want the possibility of it coming loose and falling in our laps as we are driving down the road.
