Here’s what I’d do.
I’d install a standard 7-pin, and use four of the terminals for the running lights, signals and ground, in the standard correct places on the plug.
Then set up your truck to use the other three for your camera.
Make yourself an “emergency” cable to use between the camper and truck that simply doesn’t have anything connected to the three camera pins. (Normally those will be a charge wire, reverse lights and brake controller wire, already not needed on a truck camper.
You can use that should you ever need to haul the camper on any other truck.
You can also use it if you ever have occasion to haul a different camper on your truck.
Then get rid of the six intercom wires and use walkie talkies or something else wireless for truck to camper comm.
Then you can obtain new parts anywhere in the US, which can be handy you-never-know-when.
My camper just went on an unplanned ride on a different truck a couple weeks ago when I was 100 miles from home and had an unplanned truck issue.
The camper plugged right in and made for one less hassle that night.
Incompatible proprietary connectors makes for future headaches.
PS oops I forgot to account for your backup light function
I was thinking originally you’d use the extra pin you’d have if you did use a second 7-pin for the six intercom wires.
