6v vs. 12v AGM deep cycle confusion
I've read everything here and a number of other sites on this subject and I have a mental block understanding. I get different answers from different people too -- and still don't get it. Here'...

The set up you currently have is for serious off grid usage. For your stated use of always plugging in it is completely useless.
I wouldn't spend the money or tote around the weight of big batteries if you're always going to plug in. The cheapest little group 24 or 27 would be fine for your needs.
AGM batteries are nice if you don't want to have to check the water or need to mount them in an interior space.
For your needs I would just use 1 12v battery.
6v batteries are the better choice for building a large battery bank that gets used hard. Yours will not.
6v batteries are typically build to be more robust than most 12v. They have a greater capacity for repeated deep discharge; something you won't be doing if you're always plugged in.
I build large battery banks for off grid homes. We generally use 6v batteries unless it's something really big and then we use 2v batteries. Standard design practice for off grid systems is to have no more than 2 or at the most 3 strings of batteries in parallel. You currently have 6 which is simply not a good design. It's very difficult for all the batteries to charge and discharge evenly.
