Mark,
When we bought our Monterey in '03 for full-timing, the KVH with DirecTV was as good as it got. We had one of the first flat panel TVs. It was standard definition. DirecTV provided all the cable channels and network feeds from both New York and Los Angeles. Service was spectacular!
That changed. DirecTV got tangled up in ownership changes, the switch to HD, true local channels, legal battles over what what football games you could watch and more. It got harder to get and keep a "mobile" subscription.
If you are serious about watching TV, look at what Dish is offering RVers.
