AGM batteries - are they better?
Upgrade to an AGM battery. You can safely mount them inside, and upside down, and they will out-perform any flooded battery you ever owned! Here's a quote from another thread. It's typical of other...

I would guess there are many of us that operate in the 80% to 100% range. My batteries (2 each 220amp/hr CG batteries) get charged up to 100% daily 90% or more of the time with only the solar.
Me too on solar, but the OP is talking generator time. Best there is to do 40-80s instead of 50-90s but at 40 the batts likely will not stay above inverter alarm under load.
( I have beaten that last problem by now having a separate bank using 12s just for the big inverter, so the main battery bank can now be run down to 30% if I feel like it (four 6s) Obviously most RVs can't do that where they don't have that many batteries. That is for winter half of year, no solar. Summer half gets solar and a different routine.)
