And Another Battery Question
We just got back from our yearly trip to the Cades Cove. No hookups in the campground, so we are dry camping. I equalized the batteries right before we left and after resting overnight the batteries ...

What DC load is on the batts while camping for that 12.3 that is not on at home for that 12.6?
You can't tell "90% charge" with a load on the batts. You can get a voltage but can only guess at the % of capacity, and you have to guess at the capacity too, since it changes with temperature.
Your batts are no doubt sulfated somewhat from lack of time at 14.8v and equalizations to 16v from time to time, so they might have more of a voltage drop under load that batteries in better shape.
The loads are exactly the same. That is what is confusing me.
I exercise the batteries regularly. I draw them down to around 50% and then apply a 14.8 charge while checking the SG. Equalized right before this trip.
