Sometimes small systems are plenty
Friday my wife suddenly got the urge to camp. Immediately. All the TT has is the original Group 24 battery, 5w solar to maintain it and a 700w/1500w inverter I've never even run under significant l...

I have limited internet access right now so can't waste data time looking up stuff. But ISTR we did all this last winter with extensive low voltage tests and excellent comparative data and the AGMs won by a mile on the low voltage issue.
IAW the AGM stayed above inverter alarm 11v for way bigger loads per batt capacity than my 6s, and ISTR any 12s too.
4-6s do give you the ability to handle your high loads when down near 50% SOC, where ISTR from previous tests 3-12s would do the same (but you can't have three 6s) so kind of "not proven" (as in Scotch law)
I would rather have 6s than 12s and I would rather have batts I can use an hydrometer on, so that solves that for me. There are all sorts of good reasons for an RV to have AGMs (side mounting, tongue weight, etc) but not my concern, thank goodness.
Point is we already did those tests.
