We've had DirecTV for years and like the RECEPTION we get. The HD quality is the best, especially compared to most cable companies, many of which are only giving you 720p, compared to 1080.
For us, the local channels really aren't a big loss. We still get the west coast feeds of ABC, CBS and NBC no matter where we're located. We lose three local stations we rarely watch. There are a couple of shows we watch/record on the local stations, so they are there (recorded) when we get home.
Many like to move their receivers from the house to the RV to save money, but for us, $10.00 a month for an HD DVR that stays in the motor home is worth it. We keep movies stored on the motor home unit, so we have additional movies to watch while on the road. We don't buy any of the movie channels, but when DirecTV offers a free weekend, I'll turn on the motor home DVR and record movies I like.
Tidbit...Some may not know this, but if you're in an area where you don't get reception while camping, you can still turn on the DirecTV DVR and watch the movies you have saved.
