I am lucky enough to be in range of the market I want... Boston. A few channels only have 77% signal but they are fine. Those 3 or 4 channels are more subject to rain fade, but it's not a big deal.
I lived and traveled in my RV for 5 years. The old RV package with LA and NYC was great with a dual tuner DVR I could record 4 prime time shows . I could even watch Leno without staying up late.
