I've been researching various options for replacing my Walmart 12V sort-of deep-cycle battery. I've pretty much decided that a single 12V AGM would be the right choice, given my budget and electrical ...

You also need to know how and have the ammeter for, charging an AGM to full and know when it is full. RVs don't come with that ammeter for one thing.
If one 12v will do you, IMO just get two 12v WalMart flooded ones for the same price as the one AGM. You get way more AH, you won't be deep cycling as deeply, so the battery will do better just from that (shallow cycles are easier on the battery), and you don't need to fuss with or learn anything about AGMs.
I have gone AGM for various reasons, but I also have the ammeter, the right charger, etc, and the time to take care of the AGMs. It is not the same as having Flooded batts. I have done it both ways.
I went to AGM because I need to have them inside the rig, where fumes from Flooded batts are not acceptable. Otherwise, I would have stayed with Flooded.
