I think it is a bad idea to travel with TV'S hanging on the walls, so I never do it. I bought these mounts which allow quick removal and multiple mounting areas. Additional wall mounts are available for $12. I have 3 inside the trailer, one set up for the outside of the trailer and two in the house (computer room and garage) When we are not traveling the TV can be used at home.

Call for addition wall plates.
I used a 1x6 in the front bedroom and a 2x4 in the garage. And a 2x4 for the outside mount, which I store in the front compartment, it's there if I want to use the TV outside. Black felt, glue and a staple gun. Cut the pieces very closely, so they fit tightly. Hand file them so they are wedged into place. I did not bolt them on a 200 mile trip. They did not move. After the trip, I used small "L" brackets to secure them for piece of mind. I do not tow with the TV's hanging, this set up is not designed for it.
I mounted one directly to the wall in the living area, just because a wall stud was readily accessible. More pictures next week when I take the trailer out.
Not to confuse anyone, the first pic is the outside mount. it is not bolted to the trailer. I did not want holes on the outside.
