Sirius satellite radio

You will need to get another sat antenna, and locate it somewhere either above the camper, or where the camper does not obstruct the antenna. Any store that sells sat radio equipment (Fry's, Best Buy, etc) will have the micro antenna. Install it either on the hood of the truck, or on top of the camper. You will need to run the antenna to the rear of the dash. They make Y couplers that will allow you to run both the OEM antenna and the extermal antenna at the same time, and it will not hurt the system to have both wired in at the same time.
