The TV mount I used I got at Camping World..It is the one with a chain hanging down a bit on the bottom with a pull ring and a pin locks it flat (or as flat as you can get it) against the wall...Look on their website and it is clear the one I am referring to........I anchored it to a 12x12 piece of hard finished plywood and anchored the ply to 2 stringers I found in the wall by trail and error.....

I still found it necessary to still tighten it (for travel) against the wall with 2 velcro straps that I anchored to the mount, out of sight when not in use...without the straps it is just too unstable for me....
