Do you have a periodic exercise run programmed in?
Do you have it programmed to start as a load shave feature. (I forget what Magnum calls that.) Did a mouse chew thru some wires and make it short out somewhere?
Do you have it programmed to start at a certain time?
It's quite possible that you have accidentally programmed one or more of these reasons for it to start.
If the rv was plugged into it's 50 amp service wouldn't that make all your points null ? Except for the mouse theory !
