In the TT with 2 T-105's I charged a couple of hours every couple of days, when the batteries got down to about 50 or 60% soc. I would bring them up to about 85 or 90%. I would stay out in the forest for between 2 and 4 weeks. Properly charge them when I got home. That seemed to work well enough.
I plan to use the same criteria in the motorhome - recharge when down to 50 or 60% and try for a target of 85 or 90%. Since I'm only guessing how little power I can get by with in the motorhome, and how much the solar will replace, I'm sure experience will be instructive. We plan on going camping in the mountains beginning this weekend for maybe 2 weeks.
