I find it hard to believe that the TIPM can shut down a single backup light on the camper when they tied together on the same wire in the circuit. I’d be more tempted to believe that it is a poor connection in the common white ground wire that the right stop/tail and right backup light share. Does the right tail light portion of the light assembly work? If so, I’m baffled. That is, unless the lower current tail light portion is finding enough of a path to ground to illuminate? You do have LED lights, correct?
If it were me, and I didn’t have a volt/ohm meter, I would go low tech and try to verify the possibility of bad ground by grabbing a wire, ground it to the truck and connect the other end of it to the spice where the white wires at the right rear light assembly come together to see if any lights work. If anything lights up, I’d assume it’s a bad connection/splice on that side of the harness.
By “loading lights” are you referring to what Lance calls the “docking lights”? The docking lights appear to be on a separate circuit; the truck’s backup light wiring does activate a relay to turn those on, but they do not appear to be in the “bumper wire harness.”
