Honest question--I don't know---can a single 12 house as the Aux, start the Diesel engine, which now has two 12s for it, if those two 12s are dead?
It is all in the switching. Via battery switches you can use or combine any battery bank for any purpose.
I have a boat that had 6 grp 31 gel cell batterys arranged in 3 battery banks. I could use any of those 3 banks for starting, house or all together. The drill was to put all together when running & take one bank out of line when anchored leaving the amperage of 4 grp 31s available for the house. Something like having 6 6V GC batterys.
If you like to dry camp battery power & water capacity are king.
