2006 340 shore power question; if I’m connected to shore power, should all three of the switches on the upper right of the the cabin electrical panel be on (energize) or off (de-energize)?
Not sure where you are in Florida but if you don’t run the AC buy a small dehumidifier and run that. The moisture with the AC off is bad. And even with all the Batts off your bilge pumps will run.

When I leave the boat, it's always connected to Shore Power and the Main Battery Solenoids are always Energized. I would only turn them off if I was at a marina where power was iffy as you could easily return to find batteries are dead.
