I don't have a trailer, but a coach, but I would believe Jayco does the same thing in all units. I used a stud sensor to sound out my wall to see how big the wall support was at that location, it definitely extended wider than the sticker.
I installed a bracket that slides up and off if I want, thinking I might fabricate a bracket/mount to use the TV outside too. I installed a Vizio 32" flat screen and we took one trip already, and the TV is still up on the wall, so there's no issues.
As long as you stay close to that sticker on the wall, and don't use long screws (my bathroom was on the other side too) you should be OK. If the screws are too long that you use, you'll have something to hang towels on in the bathroom!
