I have Dish for our MH. I find the Dish representatives don't know much about it. Basically you buy your receiver and antenna and then sigh up for a plan. No deals, you pay full price for the service. When you aren't using your RV, you cancel the service and if there's a balance in your favor it is held on your account as a credit. When you're ready to go again, call and reactivate the service and pay the amount needed to bring you up to a full months service. It's a good plan and we like it. You do't have tp buy your hardware from the website above; I got mine from CW. You may be able to sign up for the service through them. I have the medium plan at about $45 a month.
