Do you have a system at home? We use direct at home and when I leave on a trip I take the bedroom receiver with me. It's already programmed with the DVR catching shows just like home. And, it's not costing me anything.
I wish I could help you with the switch. I gave up on rooftop on my new coach and have an automatic in the basement that I sit on the ground. When you camp in the midwest, the trees drive you nuts.
