I have a 2011 3500 Laramie on order. I did not order the backup camera because I tow a 5W. What I wanted to do was order the backup camera cable and run it to the front of the bed to a camera to see the 5W when hooking up. Parts breakdown shows the cable. However when I tried to order the cable, I was told the only way to get the cable is to order the whole system, big bucks. I'm sure if the cable goes bad, there is a way to get the cable. Anyone have some inside scoop that might help ?
