Fair enough. I keep a camping log. Last year I camped 150 days. That's typical. The batteries still cycle when I'm not camping. I got ~0.5A quiescent load. Very rarely do I need the Iota to charge. With tilting in winter, 130W of solar is adequate. Haven't been on shore power for 7 years.
My two GC2's are over 4 years old. As mentioned, other than water, I don't do any maintenance. For the heck of it, I found a hydrometer and just took measurements. All cells are in a close range, at 1.250 or better (in the green zone).

8 years, bah, talk cycles, months holding batteries in float mean nothing. If batteries in an RV are lasting 8 years they are obviously not being cycled much, or deeply when they are.
