We just purchased a 1999 fleetwood tioga. The previous owners didn't really explain things well. Our question is what does the 2 deep cycle batteries inside the rv do exactly? We set up camp at campgrounds that offer on site electric and even if we need power we already have the built in generator. So, why the 2 batteries inside the rv?
 
Congratulations and welcome.

Those batteries are what powers your inside lights, water pump etc.
 
The shore power provides power to your converter which supplies 12vdc to your RV and charges the batteries. The batteries would give you lights etc without shore power.
 
Maybe I'm just an idiot but don't the lights and other things work if the rv is plugged into on site electric?
Electricity from the pole is used to charge your batteries and to run AC items. Your lights and water heater, etc, run on DC current from the batteries. Your converter converts AC current from the pole to DC.
