Look into DC/DC battery charging. I use a generator with a WildKat converter, but if I had to charge batteries off the tow vehicle I would run dedicated cables to the rear and use a DC/DC charger connected directly to the RV batteries. I've used the Blue Seas stuff in the past. You won't ever get enough juice from a 7 pin connector terminal to restore a full charge. Thats mainly a power source for the tiny emergency brake batteries on utility, car hauler or whatever trailers. Its not hard to set up DC/DC charges, not really expensive either. But a solar charging system may be a better choice in the long run.
