Hi, I have a motorhome on a Ducato X250 chassis with the 3.0 litre engine and Comfortmatic gearbox.

Can anyone confirm what the typical drain current from the engine battery should be when the ignition is off and the van is stationary and locked.

Depends on alarm, stereo etc. 30mA wouldn't be bad. Some aftermarket alarms are heavy on the huice, a simple led is 30mA so a disconnected phone charger left plugged in / obd device / alarm / disctribution panel left on could have you over to 100mA.
