Just mounted the Onan 2800 with the anti-vibration mounts and the hitch.
The Rear view cameras and 7" screen works great. One camera is pointed down with wide view, the other is pointed back with a little narrower view. Switch on screen to toggle between screens, one for backing and the other for driving.
