So I don't know much about those 6 volt batteries.
What I can say is our Class C as it came from the factory only had room for a smallish house battery under the hood. I forget the size.
But it would not run the furnace for a weekend outing.
So, I added a larger Group 29 12VDC battery in one of the under-house storage compartments, and wired it up with the existing battery under the hood. This gave us enough battery power to run the furnace at night for the weekend.
When these batteries died, I ditched the smaller under-hood battery and replaced it with a terminal block, and wired this to a pair of Group 29 12VDC batteries in the under-house storage compartment. Because they were in close proximity it now made it easy to have the + and - main terminals connect to the + terminal of one battery and the - terminal of the other battery, which is the proper way to gang two batteries together:

The new setup easily runs the furnace all weekend long as needed.
