We have DISH TV (about 5 months now), switched from Direct. Our home has 3 receivers. One is a dual receiver, the other 2 are singles. When they came to install DISH, we purchased another satellite dish and tripod from them. One of the single receivers in the spare bedroom has made it's way to the camper. Once you've done it, setting up the satellite dish is not hard, sometimes time consuming, but not hard. So, set up the dish, connect to the receiver, connect the receiver to the television and that's it.
The only down side with our plan, we get local channels only locally (central Indiana). If we travel outside the area, we get all the other channels, like always, but the local channels (ABC, CBS, NBC, FOX, PBS) don't come in.
That's how we do it.
