Hi Ade
Not a daft question ... Just an often asked one :wink: anyway welcome to MHF and here is a Quick answer :
if your Duetto is "as built" ( no user mods) operating normally and with all the fuses intact then Yes, the Leisure battery will be charged when the engine is running. The "3 way" fridge will also be powered on 12v while the engine is running.
On a hook up the leisure battery will be charged and power provided for the 12v items from the power unit/charger.... probably a Zig unit on your van.
