I have read a lot of Maine Sail's posts but had not seen that particular one. I am very familiar with the temperature-related aging as I was able to access and read battery stats from my Nissan Leaf and could see the effects of our hot summers on that car's battery capacity. Unfortunately this van will be stored out in the sun in 100+ degree weather at times, nothing I can do about that. I used similar charging practices with my Leaf to what you described for my camper van--I rarely ever charged the car and left it at a high SOC.
The van will be used roughly every-other weekend and one trait I really like about LiFePO4 is the fact that I can bring it home with a partial charge, park it (for a week or two) and not worry about keeping a lead acid battery topped off. I will likely shut off everything when it's parked and turn it on a day or two before a trip to 'fill' the battery. If I had a boat that sat for months I probably would do the very low voltage float you suggested.
At the end of the day, it's just a battery and I plan to use it. I like learning about technology, hence this thread. But as stated, one challenge I'm finding is the two different charging devices produce fairly considerably different SOCs based on the path taken to reach that target voltage (charge rate, time, etc).
