On the drivers side there is a white vent behind the rear bumper where the bumper wraps around the side of the truck. That vent is an easy way to run coaxial from inside the truck to outside the truck without drilling a hole. If you mount on the passenger side, I think you'll have to drill a hole or try and route the cable under the rear hatch weatherstripping. I think people have been able to run cable under the weatherstripping but it didn't really look like an option when I set up my CB.
