I charged the battery a couple days before we left. I haven't checked water levels. The battery is only a year old
I leveled and switched to LP at the same time. Not sure I can absolutely conclude that leveling was the problem. Not saying it isn't, but I'm not entirely sure that's the cause just yet.
Let me see if I understand this correctly. The light inside the refrigerator is working and has always worked. The power to the fridge can fail and the light can still work? Everything else is still running on AC.
You can have loss of AC power to the fridge and the light can still be working. The interior light is powered by your 12V system, as is the control board.
A hand-held multimeter is a good tool to have for working on RV electrical. Harbor Freight sells them for less than $10 or sometimes, gives them away at sale events. I'd suggest you have one when travelling.
