Phil, thanks for the informative response! Since I started experiencing my issues, I keep wading deeper and deeper into this battery situation. I really can’t find anything wrong, so I’m wondering if there could possibly be an issue with my solar controller. I almost never hook up to shore power, so if that controller is doing something weird, maybe that is producing my problem. It shows both the voltage and % of charge, and both have been down very low after only minimal usage. I think I will definitely go with the battery monitor just to be able to see what individual items in the camper are using, and what might be draining the battery so quickly.
I just don’t think under any circumstances that some LED lights, a Fantastic fan, and occasionally the water pump should take my batteries from 100% to under 50% in less than a day.
