Xm radio interference

Your TC over hang will definitely interfere, especially depending which direction you are traveling. I bought this magnetic antenna from Best Buy. When Im not using it I slap it on the underside of the hood and it stays put. When I load the camper, takes me less than a minute to unplug the factory antenna and plug in the auxillary antenna. Lift the hood, remove the antenna bug, and place it on the top of the hood.
