Vin it depends on how your caravan is set up! Many of us have our caravans running fully on 12 volt from the batteries; particular if they have solar panels. I have no lights that operate from mains power; they are all 12 volt from the batteries. What about your fridge? Even if you have a gas plus electric fridge, it may require the battery to run on 12 volt when travelling.

The battery may also be used to operate the electric brakes on your van, if you have a Breakaway setup, ie if the van for some reason, gets disconnected from the tow bar and the breakaway cable is also disconnected the Breakaway/Battery will operate your electric brakes if you have this set up on your van.

Perhaps it would be more helpfull if you give us the brand of the van you have.
Vans that have hot water systems with pressure pumps need a 12v battery so that these items can work when the van is not connected to power...240v.
