Charging a Battery Bank

EDIT--I would rather do a generator recharge every second day (for twice as long) on 4 batts instead of every day on 2 batts. However, if campground gen times are too short for that, it is not an option. It also depends on whether you can get by every day on just two batts. (Furnace alone here in Jan/Feb with temps just above freezing, costs me about 100AH a day, so I take 6 batts for that so I can still recharge every second day)

That's certainly understandable for those such as yourself who rely so much on battery reserve but I still question the OP's rationale for wanting four GC-2s when he previously said -

"We usually stay at State Campgrounds with Electric hookups and the occasional private campground with full hookups. I've looked at the Champion generators and they get good reviews. I know most people suggest the Honda and Yamaha generators but to be honest, they are a little pricey for me and I'm not sure how much dry camping we'll be doing. I'm sure we'll do some but I don't know if it will be often enough to spend twice as much money on a generator."

That probably describes a lot of us so kudos to the OP for questioning the value of a premium priced genset like a Honda or Yamaha ... many of us would. However, that doesn't explain why someone who would only occasionally dry camp is so willing to invest in four GC-2s when that amount of reserve may never be needed for his style of camping, particularly if he doesn't also have the means to efficiently recharge such a large battery reserve in a reasonable amount of time. :h

To be clear, this is not about challenging the OP's intentions as obviously he can do whatever he wants but I suspect many others reading this would benefit by understanding that adding more battery reserve brings with it the need for equipment rated to efficiently maintain that battery bank, equipment that many including the OP probably don't own.
