Just wanted to add another data point. My batteries were replaced on October 21st of last year after the yellow service 12v msg. I just got the replace 12v red battery msg. Luckily, I already have an appointment on Friday to get new tires and retract the stick tonneau cover. I will update...
Was not today, but pretty recent. Just over 700lbs with the lift and bike in the bed. Went from Tampa to The Dragon and back. I think it was just about 2.2 mi/kw.
