    We haven't traveled under those exact circumstances so don't have a definitive answer. However , your tow vehicle should have a charge circuit that will keep the batteries up while driving. Then over nite power consumption will be minimal if you open the fridge as little as possible.

    There is one dedicated battery for the inverter. The other battery is isolated for the coach.

    They will both charge from the tow vehicle as long as there is an active charge line on the vehicle.

    This has always been my concern. Sometimes we travel long distances over a two day period with a 5 to 6 hour overnight stop at a Walmart or truck stop. Can this be accomplished?
    With two group 27 batteries we could go 10 to 12 hours and still not drain the batteries. When you lose power in your house how long will stuff stay cold in your fridge by just limiting the door opening? I traveled 8 hours with the inverter off in 80 degree weather and everything was still cold and frozen. One of the boondocking tricks are to turn off your inventer at night to save on battery power and leave the fridge closed.
