You get more total capacity merging all deep cycling into one bigger bank, Peukert effect.
Ideally all charge sources go to the one House bank, top off the Starter from there, hardly any charge needed if dedicated to cranking only.
Are you able to self-jumpstart from House if Starter batt died while boondocking?
My main battery used for starting is dual purpose group 31 with 103ah. I can really run the fridge off either setup, but it will primarily run off the dual purpose battery from the engine compartment. I do have the ability to jumpstart from the house batteries using the smart isolator. The accessory panel in my cargo area that I'll be running the fridge from is a dedicated line from the Blue Sea panel in the engine compartment that is not dependent on the ignition. I'll be adding off-roading lights to this fuse block at a later time.
I top off the group 31 with my Noco charger every 3 to 4 weeks to compensate for the alternator not putting out adequate voltage for the agm.
