Only the things in your RV that work off of 12 volt DC, use the battery. You have a 120 volt AC system also in your RV, which also includes the converter (which converts 120 volt AC to 12 volt DC). The 120 volt AC items have to have a form of 120 volt AC shore power/generator.
This thread may help:
Your converter is your battery charger, but it also has to have 120 volt AC to work (the converter does not recharge the battery while you are towing). Are you plugging into shore power anywhere?
