I found this Mastermount 403L that looks like a good fit for the trailer but the construction of the refrigerator wall is a little mysterious. I thought peering through the outside vents would help, but it's paneled on both sides. It does feel like there's a 1x2 "stud" running the length of the the wall, maybe 15 inches back from the inboard edge. Is that where the stock mount gets anchored? I am also thinking about mounting it on the notched kitchen wall opposite. It would be partly exposed, but I can access both sides for a backer, and I like to sleep facing the door (call me Al Capone)
Here's the link to that mount. It was about $68 at Camping world, this is the .PDF installation document.

My TV is a 19" Insignia NS-19E430A10 from Best Buy that I found on Closeout. I liked the fact it uses a 12vdc input through a small AC adapter
