My experience is that the new digital TV reception is very, very picky. Unlike the analog systems of the past, there is little, if any, fringe area, either you have it, or you don't. That said, as you mentioned that you would be dry camping
, I'd opt for the most sensitive antenna, on a mast, that I could get.
Back a few and many years ago I had those built-in antennas in molded fiberglass Sunrader mini-Motorhomes and, other than in town, they were poor at best. But the one molded into the deck lid of my 1954 Corvette, worked great, as an AM radio antenna anyway.....
