I purchased a swinging TV mount for our 34RL Cedar Creek to improve the viewing when sitting in the chairs. I purchased a MORryde Swing arm, part number TV1-006H plus a 400mm mounting plate part number 24-0113 TV1-008 from TVforMYRV an on line supplier. The Swing arm has a locking mechanism that retains the TV in place when traveling.
I have installed this in 2015 and I have never had any issues with the swing arm holding the TV in place.
I just checked on line an Amazon has the one I purchased plus the mounting adapter.
