Normally the main 20 amp fuse is a blade type fitted in the +ve wire from the 12 volt battery.
It is usually fitted as close to the battery as possible without actually being within the battery box.
I would look inside the caravan behind the battery box and trace the +ve wire to find the fuse.
It should be within the first 30 cms. and readily accessible.
