GM accessory cameras

For those of you towing with a GM and purchased the aux rear vision camera for your trailer, How did you run your wire for your set-up and how does it work? I would much rather prefer a wireless set-up but that means having a separate monitor on my dash which is somewhat redundant being that I already purchased that technology in the infotainment system. If I go hard wired I don't want to see wires running down the back of my rig but then again I'm not going to drill holes in the back wall of a new RV either. Would have been nice had GM just went ahead and made the system wireless. I could care less about the invisible trailer feature I just want top see behind my rig. What would be perfect is if I could somehow run it through the tailgate camera so it would show in the electronic rear view mirror. Guess that's asking too much though.
