I'd guess you'll be able to find a place with enough structure for that...assuming the TV is pretty light. Most are these days.
I don't have drawings of the structure in my roof sadly. The only thing I've seen is that the metal frames wrap around all four sides of the penetrations...4 sides around AC, roof vents, skylights, etc...
I'd assume those points also form the cross beams spanning from one side to the other.
One thought outside the box a little....one of the features we like about our 31L plan is that the large living room tv is mounted as a door for one of the double kitchen cabinets. It puts it in a great spot and not in the way of anything.
Good luck!
