I want flooded lead/acid because they are so much cheaper than AGM. And I believe the longevity is about the same.
I want to dry camp with some furnace use, a few lights, inverter to run my tv and laptop and phone chargers, have my dual batteries last at least overnight - preferably 2 - before needing the generator.
I got that with my two dual-purpose Interstates but now that they've worn out I am looking for something better. I can't use golf cart 6V batteries without some modification of my boxes and cables which I would rather avoid.
