So, I decided to let the battery charger sit overnight. The batteries then charged up to about 12.6. I disconnected and went for a 30-mile drive; batteries went up to 12.8-ish. I then turned off everything and let them sit. They have now been sitting with no SP or anything else and the latest reading at 5 tonight was 12.51. Apparently, they were so discharged that they weren't able to be recharged using the SP.(?) Does anyone have a theory on why that would be?

Either way, we might be good to go. I'll tell my service department about this issue when I take it in in 10 days for an unrelated fix and see what they say.

You are probably okay, I put a display on my 12v line and mine read 13.1 volts most of the time when on shore power or in use mode with engine running. When I was looking into my battery issues, I learned that each time a battery is discharged way below 50% it decreases their useful life, that said, I try to keep mine above 12v when dry camping. We are in SoCal and dry camp a lot in the winter. I bought a new Honda eu2000i from a friend for $700 to take when dry camping. It'll running everything but the ac, is quite, good on fuel and easy to store. Good luck!
