similar situation, small TT with no labeled TV mount area. I even asked at the dealer before a took the TT home, and there wasn't a ply backer anywhere. There's a cable/sat plug near an outlet, right by the counter top but I don't want to just have a TV on the counter all the day. My solution (haven't done it yet but plan to this season) is to mount the TV to a cabinet, above where the radio is mounted. That way I can access behind the TV and ensure there is a backer and proper support to keep things solid. On my TT it's basically an empty panel with dead space behind it anyway, there's wiring for the radio and antenna in this space.
