Battery sugesstions

We boondock a lot.  Our favorite campgrounds are in National Parks and have no hookups.  (Not like boondocking in the middle of nowhere, but still, no electricity, water, or sewer.  The campground roads are paved and there are restrooms with flush toilets though.  No showers.)  We have 1 12v battery, but we also have a generator, and depending on where we're going, I take a Renogy 100w suitcase.  There is no limit as to how long we can stay out as far as battery power is concerned.  Two 6v GC batteries might smooth out the cycles some, but they aren't needed in our situation.

A generator is a lot to lug around and you can't use them during quiet hours, or at all in some campgrounds, plus, even with a quiet Honda or Yamaha, they annoy people.  They conflict with the concept of getting away to a quiet campground in the mountains, desert, beach, etc., even for the people who have them, at least to some extent.  So they aren't for everyone.  Some people have to have air conditioning though....  (We very rarely use the air conditioner, so we might run the generator for an hour or two a day, to make coffee and top up the battery.  Even that is moderated depending on how many and how close our neighbors are.)

No matter how many or what kind of batteries you have they will eventually need recharging.  Solar can be a very viable solution if you don't need more than a few watts of 120v AC, which you can get from a 400w inverter.  (To watch television, for example.) 

Towing all day seems to top off my battery pretty well, but that doesn't work when you're at your destination for 8 days.  Without very careful and stingy power management, 2 6v GC batteries won't last that long. 

I started out wanting to say that 1 12v battery will work just fine as long as you have some way to charge it up every day or two or three.
