After giving it some thought for sometime. Some concern over heat that my vent through refrigerator vent. So, I conducted a test. I ran the fridge on propane for 3 hours. I tested the temp at the vent and the exterior trailer wall 6 feet away and there was no difference.
I mounted the TV mount to the plastic refrigerator vent with 1/4" bolts and 1" fender washers.
There is a outlet behind the vent that the refrigerator plugs into. I turned it into a double outlet and can plug the TV in there.
There is 4" of air space between the TV and the Vent I found a 32" TV that only weighs 9 1/2 lbs. Obviously the TV will be removed when towing. It works great!!! I should have done it sooner.
