I have a 32" with a built in DVD that I thought would work well for the trailer. The info on it says it weighs 19.5 lbs so not too heavy. I like the strap idea. My wife and I are hoping to test run the new unit this weekend coming.
I installed 2 straps with adjustable connectors on the wall behind the TV. While traveling I run one over the top and one under the bottom of the TV and connect in the middle snug against the wall. Never had a problem
