What's the purpose of a battery in a camper?
Why does a camper have a battery? You don't have a starter. If you are always connected to shore power, why do you need one? Maybe if I boondocked, but the power from a battery isn't going to do much ...

Actually we don't have a winner as newer converters don't need a battery at all. This is not conjecture, this is fact. The OP said he only does full hookups so it would be best if he posted make and model of converter. That would tell us if he needs the battery or not. Personally, I'd get a battery regardless just in case the park loses power. That will at least let you run the furnace for a night.
