I don't have your model trailer, but we also wanted to add a larger TV in our bedroom where the TV was too large to fit in the designated area, which in our case was between the ceiling and the window valance below.
Bought a tilt/swivel/articulating arm/removable TV mount that allowed us to hang the TV while in use, and we just removed it from the mount and laid it on the bed during travel. I also liked that the wall mounting point was narrow because in our trailer, we only had a 3" wide vertical strip of wood to screw into. Here is what I bought and it worked great for us.
