The shore power outlets are generally 30 Amp circuits... so you need to have a distribution breaker that can handle that kind of amperage. That's why the two top breakers are needed to kill the incoming AC feed—essentially acting as the main switch on your home's circuit panel.

If you get a battery combiner, like the BlueSea ACR, you can use a single charger to charge both banks. The second can charge two separate banks without a battery combiner IIRC.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
