I would check with folks who have a Dome and see how they like it. We've got friends who hated their Dome and changed it out for the Winegard DirceTV SlimLine dish and love it. We had the Winegard Travelr SlimLine on our Montana, and had one installed on our RW before we took delivery. Yes, everyonce in a while you'll have trees in the way, but more and more CGs offer Satellite Friendly sites if you ask.
