Any of y'all figure out a way to move your backup camera to your cap's third brake light?

Yeah, both the anytime mod as well as the plug and play cameras seem like good options for the connection. I guess I'm looking for ideas on the actual mounting of the camera to the cap. Finding a 3rd brake light with a built-in camera for the cap would be ideal because no holes would be drilled; but I can't find one for an ARE CX. Drilling a couple of holes below the cap brake light for a bracket is another option. I'm worried about leaks though. Could also mount the camera inside the cap, looking out the back window, but that has it's own problems. Another thing I've considered is mounting on the cap rear window rail that goes on the top of the tailgate, near the lock. Wondering what others have done and looking for suggestions
