This happens at about 10.5 volts.
It is too soft to wake me up at that distance. Maybe in a 40 foot coach it would wake you.....
We park ours indoors, unattended when not in use, plugged in to shore power, refrigerator empty but running. If the power fails for a few days the batteries will run it a long time, several days at least if no one opens the door, and then it will stop. But with no food inside, it soes not matter. We also turn off the engine start battery switches near the engine to keep those fully charged.
