That's the same antennae I use and it works great. I have one account with Dish with a Hopper in the house and a Hopper and Joey in the MH. Our account is not an RV account but a regular yearly subscription.
FYI, I called the MH a guest house when I placed the order. The installers are contract people and didn't care one way or the other.
We very much like the Hopper setup and never watch anything that has not been recorded first.
When traveling I simply call dish move periodically and have them change our service address.
