Didn't get a chance to call yet but was able to do some diagnostics on my own today. I was able to isolate the problem it to the camera. If I plug one of the side cameras into the backup camera port - it works.
I unscrewed the camera from the back of the MH only to find the cable runs into a cavity behind it. There is no slack on the cable at all and no plug or socket to unplug the camera so it can be replaced.
Now you would think FR would design and purchase a backup camera system that provides a provision to replace the camera without taking half of it apart.
It's not like these things aren't prone to failure.
