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 Duracel...

I would never go back to flooded lead acid batteries, just due to the inevitable corrosion. However AGM batteries do have to be correctly charged, or their life will be short. That means correct voltages, and for sufficient time, somewhat frequently.
There is an argument for two 12V vs two 6V: if you run an inverter with high current draw, the two 12V batteries will have lower internal resistance than two 6V, and so lower voltage drop while running the inverter.
Technically true but with only a couple batteries, you probably shouldn't be pulling 2-3,000w anyway with an inverter. If you are trying to pull that kind of wattage, you should really have more than 2 batteries (6v or 12v).
500-1000w for a cofee maker or microwave shouldn't be a problem with a pair of 6v wired for 12v, so long as you keep it down to a few minutes use.
