Go to a club store like Costco or Sams and get the cheapest 4 x 6V GC batteries. :)
Then use some of your spare time to get the real skinny on AGMs.
Last year I advised a fellow camper to replace his 4 x 6V GCs with only 3 x 100AH AGMs from Sams Club. Yes, 440AH replaced by 300AH! He dry-camps mostly. Yes, we are still good friends! :)
In fact, last week he had a lot of praise on how well 300AH of AGMs kicked 440AH of GCs butt on both drawdown and especially recharge.
Please look at my profile. I run 2 x 12V compressor fridges from a single 100AH AGM. Not only that, in the morning I can draw 700W for 30 minutes to make coffee and breakfast for me and the wife. I do have a Panasonic MW, a 700W Mr. Coffee and an induction stovetop that were specially bought for that use. Remember, breakfast comes after running the fridges overnight. AGMs hold Volts so you don't trip your inverter.
Recharging is with a Magnum 1012 inverter/charger 1000W/50A. Yes, the charger is 50% of the battery's AH. Try that with your flooded battery. AGMs suck up AMPs and charge faster while using less genny fuel.
That's my report and it is real, not some vague un-reference to 'some reports'.
