Disconnecting the battery did stop the drain. We were driving some 400 miles a day, I figured that should be enough time to recharge batteries, maybe not. Will have the battery checked when we get to a service provider. Tiffin suggested we turn off the inverter, apparently it drains battery when on even if no 120V appliance is plugged in. Holding down the DC breaker button did not turn the breaker off, will need to resort to taking wire out of breaker to cut the circuit. Now back on shore power and recharging batteries, we'll see what happens next week.
