I can't speak exactly about the unit you're buying, as mine is the smaller 23A.
I'm going to assume your problems with mounting a TV in the bedroom area will be these two; routing a cable for an antenna and powering the TV. mounting the TV shouldn't be a problem, a flat screen isn't that heavy depending on the size. If you mount it under an overhead cabinet, for example, you could tap into a light fixture for 12 volts. If you get a TV that runs on 110 volts, you'll have to either be on shore power or the generator to run the TV. So buy a TV that runs on 12 volts and you'll bypass that problem. (TV's that run on 110 volts have a transformer in them to convert it to 12 volts anyway).
I will assume you'll have an antenna on the roof, which means you'll have to add that. You'll have to run an coax cable from that antenna to the TV, and you'll probably want to power that coax to amplify the signal so you'll need power for that (12v). The roof vent for the refrigerator will give you a path from the roof down to underneath the unit so that's a good way to run the coax. From underneath the unit you can go into the storage area and then up to the bed.
A bedroom TV can be done, but you'll need a antenna that rotates to get a signal and you have to be within 50ish miles from the TV transmitter or stay in campgrounds that have cable available. If all you be using the TV for is to watch DVD's, then the installation will be much simpler.
Or, you could get a tablet that operates on 4g and then anywhere you get a cell signal you'll have entertainment from anywhere in or out of the TV. It's what I do.
