You are absolutely correct.

I took the photos 7 years ago and my eyes saw what my brain expected to see. (Same thing happens with my eye-stomach connection. )

I don't know about the specifications. I connected them in series. They each have an internal 300 amp mega fuse that is serviceable. The continuous amp rating is 175 amps.

Thanks. Their website doesn't provide any hint about the on-off switch function, even for the OWL model, so I guess it will remain a mystery.

True, some circuits are not supplied through the power centre, so they are not disconnected by the storage switch. This usually includes the landing gear or tongue jack (because they save a long wire run by just tapping into the 12V line from the towing connection); this doesn't cause the battery to run down because the jack consumes no power when not in use. A detector (CO or smoke) could be a problem in storage.
