You have a rather un-orthodox procedure of swapping out a weak battery in the middle of a camping trip, something very few people would do.
I would recommend a pair of 6V golf cart batteries. 200+ Ah. If you buy them at Sam's Club or Costco, I am sure they will cost less than those NAPA Group 31 batteries.
Always plenty of talk about a single 6v battery failure and you are sunk. So they want two 12v batteries. However a bad battery can drag both down so I see this as perfectly logical and should be common if the single bad battery is a concern. If I did this I think I would have a switch to select battery 1, battery 2, or both.
