To find a "drain" use a voltmeter on the batteries or where the main 12v comes into the panel, without connected to shore power or generator. First check with all fuses/loads removed, then add back one fuse at a time, watching the volt meter. If all loads (lights, refer, etc.) are off you should see a drop in voltage when the suspect circuit is engergized. Once this circuit is identified see what's connected to it, may be something is "on" that you don't know about or there is a partial short that's enough to drain the batteries but not enough to blow the fuse.
