You SHOULD not get DTV for your home.. Get it for your RV, then put the spare receiver(s) in the house (you will need to either obtain your own antenna (Dish) for the house or use the portable one for the RV and you will need to do your own cabling...
Why is this: Home accounts do not qualify for Distant network Service (DNS) and thus since locals are usually spot beamed, if you move too far from home you can't get those all important daytime drama shows (Or evening action and mystery shows).
An RV account qualifies.. Here is another suggestion,, IF you have a DVR of any kind subscribe to the DNS city on the OTHER side of the country.. That way you get two shots at Prime Time,, In eastern time that is 8-11 pm and 11p to 2am
In Pacific it's 5-8 and 8-11 PM. You can double your pleasure when at or close to home.
What I did by the way (But then I did not have Sat in house).
What I do now.. I have so much over the air TV I can't watch it all, Had to haul about 200 hours of movies off the one DVR and store 'em on this laptop (Which has the space for now) and try to find time to watch 'em when in the land of no good TV later.
