I asked this same question back in the summer. We don't boondock, but we do have a residential fridge. I got a similar reply, and I read a bunch of threads.

In the end I went with 2 6 volt GC2's from Sams Club. They were about the same price as the RV/Marine batteries. I really think for my use, it really probably doesn't make much of a difference, I went 6v just to see how well it worked, and figured with price being the same, I didn't have much to lose, but there did seem to be alot of people talking about getting longer life from the 6v.

Unless you boondock just pick one and go camping and enjoy!

even a residential fridge probably isn't an issue with GC. It's when you get above a 30-50A draw that the GC start showing the limitiations due to internal resistance. I have a dorm fridge I run in one trailer on a pair of GC. the GC handle in short inrush no problem and the actual draw is way less then the nameplate. I see 8A or so as the continous draw.

It's microwaves, toasters, coffee pots, tea kettles, that can be frustrating with GC batteries. Things that are drawing 80-100A

Go with 4 6V GC-2's and as long as you keep them charged up, high drawing appliances like micros, toasters, hair dryers are no problem(for a reasonable run time) when dry /boondock camping. It's the only way to go.
