House batteries not up to ah rating
Bought 2 new Interstate SRM-24 group 24 RV/Marine batteries a few months ago. I have used the MH 4 times on trips lasting from 3-6 days. Never going below 40 amps before recharging. The rating is 85...

I'd double check and verify cells 1,2, and 3 again on battery B with the SG meter. Otherwise, you've gotten them all back where they need to be, especially with this 65 to 70F temps we have today. 1.280 is about as good as it gets.
3 to 4 days of bubbling at low amps and 16.15V is what it takes, I guess, from the 4 or 5 camping trips you went on.
When I worked for Sears Roebuck in the late 1970's, batteries that were discharged were put in back on a charging rack, and the customer was given a loaner battery, with the instructions to come back in 72 hours for their battery.
There's something to that low and slow amperage with high voltage to get things fully back in shape to top charged and desulfated, and the battery chemistry back to the correct range.
