We have a 2015 Prowler P292 5th-wheel trailer, and I have two swing-mounts that I bought at camping world.
I plan on getting a larger TV for the living room, but this 24" is OK for now . . .
I bought the swivel mounts at Camping World . . . one in the living room and one in the bedroom . . . and they both lock the TV's to the wall without any straps!
