When I first bought my motorhome in 2004 it had an in-motion system. It worked and my wife would use it to watch TV while on the road. She would watch the overhead which I could also see from the drivers seat, which is illegal in most states. But we never got stopped for it.
But here's the problem: I see you live in South Dakota. The satellites orbit over the equator. What that means is the further north you go, the lower the satellites are on the horizon. So obstacles like trees on the side of the road block the signal. Every time the signal would get blocked for more than a few seconds the satellite dish would go into search mode and it may take a few minutes to get the satellite again. When we were up in Northern California or above it didn't work very well because of that. In the desert in Southern California it worked perfectly.
But the real problem is the thing eventually broke and after doing a lot of research I determined they were basically junk and broke all the time. Sounds like the one you have is newer, so maybe they fixed that problem. And I wanted HD channels anyway so I swapped my dish out for the Winegard Travelor. Don't really miss the in-motion TV at all.
