GM’s trailering camera system install requires the camera to be mounted tailgate height on the rear of the trailer. And a max trailer length of 32 ft. Has anyone mounted this camera on the roof? And/or in a trailer longer than 32 ft.? How did you run the wire? I suspect it will work fine as a backup camera but the “transparent view” will not work for trailers I err 32 ft long. I also suspect it will work fine as a rear view /backup camera mounted on the roof.
