We just used regular LCD TV's and plugged them in on our 2015 261BHXL. In the bedroom, a simple articulating arm mount. Push the tv back and it snaps against the wall for travel. Pull the chain and the TV comes out when parked. For the living room, just a regular mount. I think the TV's are only 27" or so, but you can probably go up to 32" and fit.
We have no use to try and use 12v TV's, but I guess that's always an option if you need it.
This is the mount we got for the bedroom. It has a locking pin which is obviously critical for travel.
