We have the Winegard Traveler Dish 1000 sat unit and it works quite well. We have the same box,722, as we have in the house. We used to have a real problem with being able to access the programs when we set up and every time we stopped we had to call Dish and spend a bit of time doing the signal bit on the phone. I finally found that if I left the box ON, then when we pulled in, there was a minimum time till we got signal.
The only problem we have now is that Dish is in contract negotiations with Fox 13, which is the Seahawks broadcast station and they can't get together on price, SOOoo Dish does their usual tactic and we're blacked out
