Two 6 volt vs two 12 volt run time
I was just informed that two 6 volt batteries would run the residential refrigerator many times longer than two 12 volt batteries. I wonder if this is just hype?

Unfortunately it's very hard to find affordable true 12v deep cycle batteries. True deep cycle 6v batteries are a dime a dozen so cost relatively little.
As I understand it, more golf carts today are using single 12V deep cycle batteries. In due course, the 12V battery will become as numerous as the 6v's are today. Then it will not make as much sense to go to 6v batteries.
As things stand today, I will change over to a pair of 6v batteries, just because they can be found everywhere and they are relatively inexpensive.
I'd rather have a single 12V battery, but that is not in the cards, currently.

Two 6V batteries in series.......12V with SAME amp hour
Two 12V batteries in parallel----12V with double amp hour
So depends on WHICH 6V/12V and their amp hour ratings
Such a simple and clear response in a sea of fog. :)
If your 6v batteries are 210Ah, then two will give you 12v @ 210Ah total.
If your 12v batteries are 55Ah, then two will give you 12v @ 110Ah total.
Many people (and manufacturers\dealers) will install cheap basic 12v batteries. Even with 2, you are not getting a lot of amp hours out of them. So upgrading to 2 6v batteries will often give you more bang for your buck.
However, if your 12v batteries are of better quality, that significant benefit can become minimal.
