And, yes, there is a KISS mechanical solution. But, it does require an owner to know just a little about their electrical system.
Use a simple marine ON-OFF switch such as this: https://www.perko.com/catalog/battery_switches/150/medium_duty_battery_disconnect_switch/
It is rated at 250 amps continuous duty. Yes, there are ones rated even higher for a little more money.
Wire alternator output (B+) and chassis battery to one lug. House battery to the other.
Switch OFF means alternator charges only chassis battery. Switch on, alternator charges both banks. Also a good battery combine option.
Particularly if going from CG to CG where you will have shore power, kind of crazy to pay fuel to run the alternator harder to OVER-charge the house bank all day while driving.
