I just went through basically the same thing. We have had Direct for 30+ years, essentially from when they started. We got the notice that we had to update to HD receivers because they were no longer broadcasting in SD. Not a big problem, or so I thought. We have a receiver in our KS house, one in our TX house and one in the RV (which is used sporadically). Every tech I talked to gave me a different on whether we could have two permanent locations, what it would cost, and what programming we could get. They had a hard time believing we don't record stuff, don't game, don't need premium movie channels, etc.
But after several hours on the phone with them and with Dish, we are making the switch to Dish. We will see how it goes. But I like the idea of having the RV receiver on or off as we need it for $7 per month.
