I am not sure what all trailers have the T.V. "box" that swivels around to the bedroom..
We did not take into consideration that we would not be able to sllep with the bedroom doors closed. (Dogs would go nut case). With the doors open you would not be able to see the tv..
Originally we were going to install another TV in the bedroom. I wanted to try something first, and, so far happy with results. ( just installed today so cannot review the durability of the set up)
T.V. is 24 inch LED Toshiba. Toshiba - 24" Class / LED / 1080p / 60Hz / HDTV - 24L4200U
