There were some other parasitic drains on the batteries so we added 400 watts of solar to keep the batteries charged during daylight hours and limit generator usage. That helped overnight battery usage some, upping time on battery to around 10 hours.
In our new Thor Hurricane, we immediately had the dealer install two additional batteries and added 400 watts of solar panels. We have been dry camping frequently without issue but we wanted even more time so we just updated our 4 batteries to group 31 AGM Interstates. We are still waiting to see how they perform.

I REALLY like AGM batteries! I had a single Odyssey 1700 in our old coach. I liked how it would re-charge really quickly when it finally did need charged. I use a little 925 Odyssey in my race/show truck. It does an outstanding job! It spins over the 10.8 to 1 compression motor faster than anything else!
I found this Apex battery site. It wonder how good their AGM 6v would hold up?
