Firstly, I am assuming that you have attached the mount securely
to the wall. Gotta be attached to studs or from ceiling joists (as applicable). If you've got a 32" TV, that's a lot of weight including the mount.
Most RV manufacturers are using oridinary 1" velcro straps (one on each side of TV). The straps are attached to the wall with brackets. I bought plastic ones from www.theclip.com
. The clips should obviously be attached into something solid like a cabinet wall or studs.
The straps on our TV mount are in these photos. Cheap solution and works like a hot darn.
