So next trip, identical to Nov, but a month ago in January, another four days camping at around freezing. It was all six mixed bag as one bank. Result, no recharge needed until the second day and then on fourth day prior to the going home day when I did it at home. Since then all batts returned to baseline SG and floating till next chance to go camping.

A while back someone had asked me how I can run down a large bank like mine while just doing 3-4 day weekend type camping. You just demonstrated how. DW and I went to a FHU CG near the beach and it was cool and rainy the entire weekend (4 day trip). It would've required a recharge for sure during that trip if we were boondocking.
