I'm looking at getting Sirus but I don't know what equipment to get. I've got a 2002 Chevy 2500HD P/U and a 2007 F-350 both without Sat Radio. I want to have the ability to use Sirus in while I'm driving in both of these vehicles and I'd like to be able to use the Sat Radio in/around my 5th wheel. What's the best choice equipment for me to meet these requirements?

You help is greatly appreciated.
