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

Do an energy survey if you dry camp/bookdock. Then pick a battery or batteries with at least twice the amp hours of survey amount. Three times is better.
BUT if you always plug in when camping (yuck) one 24 should do you.
