switching to two 6 volt batteries?

I'm about to replace my two AF1150 batteries. They're currently Interstate Deep Cycle 12 volts wired in parallel.
I'm thinking of going with two 6Volt golf cart batteries. Sam's sells the Duracell EGC2 for 150 bucks. Specs:
20 amp hour rate: 230
5 amp hour rate:174
Battery electrolyte composition: acid
Battery end type: top post
Battery purpose: deep cycle
BCI group size: GC2
Freight class: 65
Minutes at 25 amps: 448
Minutes at 75 amps: 120
Terminal type: DIN
Volts: six

I was thinking that with the 2 two wired in series, I'd be better off on the Amp Hour rating. Any opinions?

Thanks as always

I originally went with two GC2 batteries. measure your opening for your battery compartment twice, then measure the height of the batteries. The largest I could fit in mine was 210AH as the 220AH were 1/4" too tall to get in the space. they seam to get taller as the capacity goes up. As it is, I had to a buy an auto watering set up so I could add water to them when they needed it, but I would recommend that for any setup now as it made topping off water so fast and easy.

I have since gone to LFP to save space and weight, but the 6V batteries worked good with my solar when I had them
