My camper will be setup permanent at the campground. I was planning on NOT putting a battery on it. Why should I? I'm plugged in. I've heard that there has to be a battery there to complete the circuit for the 12V system. T/F? Also, I have read a few threads here that say to have the battery for a filter for the 12V system. With both recommendations for the battery the current is direct. Power goes from the supply to the appliance. If the current went from the inverter > to the battery > then to the appliance the battery would have to be there, and the battery would act as a filter to regulate the voltage... I think. I don't know.
