The 32" Sharp in our '06 Monterey has an analog tuner; I had to add a converter box up in the overhead with the A/V components in order to view digital signals off-air. You'll probably have to add one to the 20" TV in the bedroom as well. I also bought an additional sensor to stick on the converter's front, and attached it to the existing IR "eye" so the converter's remote would work with the wood A/V cabinet door closed if needed. That would be handy for the bedroom TV also. As I recall, I think I got a "pass through" type of converter, which can pass through the rare UHF analog signals one might come across, so no matter what the source you'll get a picture.
I'm considering letting Beaver Coach Sales revamp my setup up front to improve the whole shebang; there are better A/V components now and they recommend a 40" digital TV, since that Sharp has side speakers that make for an already large opening, side-to-side. They just need to extend the wood frame ddwn an inch and a half, and maybe redo the speaker system. But it ain't cheap at about 2 to 2.5K, which includes the new components, and depends on the level of TV you want; I don't need 3D for example. But the revamp ends up with same-brand components and only one master remote, instead of 3 or 4 we have now!
As a side note, I often can't get a picture in certain areas unless the antenna is actually down! Also, the amplifier in some venues is too much power boost, and does more harm than good; so sometimes it's better with the little green lamp off up in the cabinet.
