Need suggestion for trailer wiring
I've tried running a search and have looked back about 8 months but can't find a thread addressing this. How would you suggest charging a TC house battery with the 7 pin connected to a cargo trailer ?

If the only 7 pin is plugged into your trailer how are the campers marker and turn signal lights powered?
You can add a second 7 pin to your truck. Modern trucks prepped for 5th wheels have this from the factory. On plug in the bed, one on the bumper. You could make up a splitter turning your single 7 pin into a Y with 2. The effective charging from a 7 pin is minimal and depending on the alternator load now with the trailer, camper and the truck don't expect much in the way of charing to the camper battery especially at night with all the lights on.
You could run a larger dedicated line from the truck to the camper which would help with voltage drop but again your stock alternator might be a limiting factor for getting a good charge.
