So here is my resulting setup. My rear view camera already had a custom attached steel tube arm extending from my ladder in the back (built by my father in law). So I attached the rear camera from the 360 system to that (the zip ties are to get me up and running until I get a better mount). You can see the difference in the cameras. The left one is the digital rear view mirror camera, the right one is a 360 surround camera. These are about 7ft above the ground.

The thin fakra cable is long enough (12 meters) to put the giant control box waaaay up at the tongue. I followed the same route I used for the rear view camera cable along the underbelly/skirting to the tongue. I have room in my locking metal battery box to put the control module and take up slack. In this pic you can see the rear view camera cord slack and inline repeater on the left, and the huge 360 control box on the right. My battery box has grommeted holes to send cords in/out so it ends up perfect for this application and keeps the entire system external yet protected. I strapped it down tight and added some padding after the pic was taken. But you can see only the rear camera is connected. Since it is up near the hitch I did not need to use the bulky extender cable that adds another several feet in case one mounts the box far from the truck. (for anyone interested in the lock box it is from rvlockbox dot com)

And lastly, here are my views. First pic I'm showing the rear surround camera on the Uconnect and the full screen digital rear view mirror from the trailer. You can see the field of visions compliment each other nicely, and only the drvm stays displayed while at speed. The 2nd image is my favorite view on the drvm, where the trailer rear view is center, and the side mirror cameras are placed on the sides for a running view of the blind spots. I love finally using (almost) all the tech that came with my truck!
