The only reason I have found to have the propane off while traveling was during fueling operations, tunnels that require it and using a ferry to cross Puget Sound that required it. Otherwise I drive with the fridge on auto and no problems with the batteries. I also do not charge them while traveling. I never hooked up the charge line as the house batteries should maintain a full charge for a day's travel with nothing other than the fridge and sensor draw. Everything else is turned off including the water heater and furnace.
