Thanks for the suggestion,,, that's exactly what I did. It looks to be a supply power issue. Everything is good at the panel, but there is no juice at the Black and white 10ga. 12v supply connections on the Lippert controller. I would assume there should always be supply voltage to controller itself at all times?
My theory right now is that the supply wiring got disconnected while loading chairs and such into compartments. Maybe a wire nut came loose?? I haven't confirmed it yet, but loading gear is the only thing that has been done to the camper since parking it.
