We have found this quite useful while camping and the window is not open the TV is sitting on a custom removable wall mount. The bracket on the wall is stainless steel and the whole thing travels in a custom made box in the trailer. It is also a 13" TV and I have a flap that hangs from the awning in the event of rain and a waterproof cover for when we are away.
This is only one of the over four dozen upgrades or mods I have made to my old camper
