I have a 2019 Jayco 22' C Class. is it better to have one group 27 battery or two group 24s?

If you don't overcharge them so they "vent", AGM batteries can be used "inside". (Always with that risk of course) That provides more options for location and besides keeps them warm where they don't lose so much capacity as batteries do outside, AGMs or not.
Our 1991 Class C (photo in Profile) came with a battery box to the outside that is under a dinette seat inside. That box is just right for an 8D battery. I could get two 27s in there but had to cut away part of the outside doorway to get in two 6s for height. After a while I ended up with an AGM 250AH 8D in there in parallel with two 100 AH AGM 27s under the kitchen counter next to the dinette so the parallel wire runs are short.
So we have a 450 AH battery bank, all AGMs, inside where it stays warm.
