^^ that's a valid point as well. Ill have to do some research and see what charges the battery and where its located so I can test it..

When the camper is on shore power, shouldn't everything run right off the shore power? I don't understand why some things are directly fed from the battery.. If we're seasonal, shouldn't we be able to plug the camper in and use everything, regardless if the battery works or not?

Yes you should, except in the event the converter isn't working properly as noted above. If the battery ain't charging, it's a good bet the converter isn't working properly. You have to check the output of the converter, without the influence of the battery. You should get something around 13.5 volts. To much and you fry the battery, to little or none and you won't have enough power to charge the battery and/or run 12V appliances.

You have two sides, a 120V side and a 12V side. The converter provides power for the 12V side. In the event the converter won't provide the needed 12V power, the battery will until it goes dead.
