Going to go with the the fully manual option with a 1/2/BOTH/OFF switch
Simpler:
Marine ON-OFF switch.
Alternator B+ and chassis battery to one lug.
House battery to other lug.
That way the chassis battery is always charged when running the engine AND you could not start it with the chassis battery disconnected from alternator (which would blow the alternator diodes).
And to charger both the chassis and house bank, just turn switch ON.
And, if your house bank is fully charged and you will also be in a CG tonight with shore power, leave the switch off. No need to burn extra fuel to over-charge a fully charged battery.
And, it makes are good boost switch.
