Thank you Wayne, Joe, and Chris for the input. Wayne, can you say what you bought and where you got it?
I agree that I am spoiled by the back up camera on my modern vehicles but I really notice it when I am trying to back up my '50 3600 with no right side mirror and only a seemingly small rear window in the cab (partially blocked by '99 Silverado seat head rests).
Chris, fortunately my NV3500 transmission has a switch for reverse and my truck is already 12v so not nearly as many challenges as you had.
