@Bish - It depends on how your power management system has been wired up... but generally...
If you have a DC DC Charger fitted (usually close the the leisure battery) then driving the van will charge the leisure batteries once the starter battery is charged...
You'll need to have a root around and see what you've got to work with.... maybe some pictures would help....
