I wanted to mount the biggest TV possible in the available area. After a lot of web searching, measuring and testing with a cardboard template I wound up with a 24 inch Samsung mounted on a MonoPrice 10476 Full-Motion TV & Monitor Wall Mount Max 77 lbs, 23 42 inch available at Outlet PC
MonoPrice 10476 Full Motion TV Mount | $29.98
The reinforced wall, electrical receptacle and cable jack were provisioned at ETI. I used stainless steel bolts with lock nuts & washers to install the mount so it will never pull out or loosen. You have to remove the microwave for access. I also had to trim the mounting plate to allow access to the TV jacks. It was not a problem as the TV used other fastener locations for the VESA pattern. I taped a rubber bumper to the arm to prevent it from hitting the thermostat. The TV can be viewed from either end of the trailer. Once the layout is done it's an easy install.
