Thanks for the answers. I grew up on a ranch and all our trailers had breakaway protection and all the batteries were charged by the Tow Vehicle. My VRV is wired to charge the house batteries but I need to validate that the BB is not in the circuit. I currently don't like the the house batteries are charged by the TV. I have a 235 watt solar panel on too and in a trip greater than 1 hour the charge controller shows an overcharge and shuts down but the batteries keep charging greater than 14.4 volts which isn't good. I will do some more research and let ya'll know what I find.
