Battery choice depends on how often you dry-camp, whether or not you have solar or a generator, and what items you are looking to power and for how long.
I have two group 27 FLA (flooded lead-acid) batteries, no solar, gas/electric refrigerator and my lights are all LED. I have a generator if needed, but I can dry camp 3-4 days without pushing the batteries past the breaking point.
If you are a serious dry-camper, I would go with 2 lithium 100ah batteries. Lithium batteries are lighter, more efficient and can be discharged to nothing without harm. The downside is cost. The middle of the road option is a set of 6v golf cart batteries. AGM batteries are somewhere between FLA and golf cart batteries. You can get a 100% DoD (depth of discharge) on Lithium, 80% DoD on AGM and 50% DoD on FLA.
Again, it all depends on your specific situation and needs. We don’t dry-camp very often (maybe 1-2 weekends per year), so FLA batteries are more than sufficient for our needs.
