Currently, I have an ugly rig set up that works fairly well. I have the antenna wire bundled up and tied to the arm of the suction cup mount, with the antenna literally taped to the top of the mount. Since I also have a class C, this also is a problem due to the cap. But, I was just reading that you can put the antenna inside the cap on top of a small piece of metal. I think it will be fairly easy to route the wire up through the A pillar, along the top of the door, and up to that area. Once I am sure that this will work, I am thinking I may mount the antenna on top of the TV in the cap. I will probably test this today or tomorrow, so I'll post back when I have a solution.
