Yes it's my own D***N fault
First part of this was posted Sunday on the "What Did You Do to Your Class A MH Today" Forum. Not really asking for help. Sympathy maybe. Just really a comment. Perhaps someone will learn something...

Thanks for the encouragement but:
This was strange: Checked the battery voltage reading on the Xantrex (not in charge mode as this morning, 12.6 V Removed all 4 batteries to the ground--not as easy as it sounds, it's very tight! Also took photos first and during.
Once on the ground checked each battery: 6.2V ! :h
Reconnected back to series-parallel in the exact same format, reading 12.4V! What happened to the 12.6 of half an hour ago? The DVM has brand new batteries. I'll take up another voltmeter and compare.
Here is the SG: (closest to negative post first):
A1 1.285 1.275+ 1.275+ A2 1.275+ 1.275+ 1.275
B1 1.275 1.270 1.275 B2 1,275 1.275 1.275
I'm a bit surprised to see only 12.4 volts with those S.G.s
In any case, I connected two in series (B1 and B2) and put my good old Canadian Tire charger "Smart" charger on at 40 A
I must remember to check the main cables to make sure that the tech hadn't put the Xantrex charge line on one bank and the load buss on the other. That might explain the small difference in SG between set A and B
Guess I won't get these all done today! Good thing the weather is good.
