I recently installed a Rearview Camera on my truck which I am using for hitching as well to view the front of the coach and hitch while underway. The camera is located on the truck license plate. I am going to add another camera to the rear of the coach to be used as a rear view mirror. Currently I cannot see what is directly behind the coach.
Here is a link to the installation:

Glenn, you may want to add this to the links under Show and Tell.
