This is an older Insignia TV (NS-19E310NA15) we had which just happens to work on 12 V. This is how it normally sits when we're camping.
The swivel mount is bolted to a piece of baltic birch plywood, which is in turn screwed to the wall. It swings out enough that it can be watched from the door side of the dinette. If adjusted just right, someone laying in bed can even watch it at the same time in the mirror.
And this is how it's stowed for travel. I use a bungee to hold the arms of the mount closed so it doesn't swing out when travelling. The crank for the Winegard Sensar IV antenna can be seen above. I had to shorten the mast arms a few inches in order for it to stow neatly on the roof. I also mounted a Camco remote holder on the wall. On the left is part of the solar power system.
