Same as George, but we have dual VIP722s which provides us with a separate Dual receiver for each one of our TVs. Record while watching a live program, or record two programs while watching a third pre-recorded program.. Very simple to disconnect from the house and reconnect in the rv. And like Paw Paw, we also use the DISH.com chat feature. I set up a small word program that tells them exactly what I need and I just cut and paste to the chat line. I change the service address in the word program prior to cut/pasting with our current address (usually an rv park). This eliminates any confusion you might have with the operator.
We also have the automatic and hard mounted Winegard Traveler antenna. One push of the button and it will raise and lock onto all three sats within a minute or two. It is kinda pricy (approx $1500), but boy is it worth it....especially if you have a portable antenna that you have to locate the sats by hand. Also, with all three sats in focus, there is no changing of the sats when changing channels.
