Have had this 2001 U320, over 6 years, never an issue with battery charging etc. Then I added the 4th 8D Gel to the string, so far all is wonderful.
NOW the curiosity begins, the Didital readout says 14.1 VDC, text book, howsomever my Fluke 87 sez 13.697 VDC at same time. SO does anyone know of a trim adjustment so it agrees with the Fluke ?
With the 13.697 VDC, it surely is not fully charged, assume never has been. Auto start at 12.2VDC, always very reliable, never has to since the 4th battery was added.
Tiebit: Both the old 87 & the much newer 87 agree.

I am assuming you had to remote mount the fourth 8d? Perfect battery setups have exactly equal cable runs in length. On my 97 I looked and to do it perfectly I would have to remove the battery connections on the wall in the battery area and put them on the other side of the compartment wall and then install another dual battery tray like my bottom one in the space where the single battery is now.
May have nothing to do with your issues you mention here but battery fanatics talk endlessly about exact cable setups to avoid having some of the battery's carrying more loads than the others.
My tech guru shows me which batteries he replaces in sets on high use rv's like busses as not perfect cabling setups cause some batteries to be used harder than the others and need replacement sooner than the others.
Maybe better to make up a expensive set of cables equal length to simulate a in the same area location and coil up the extra cabling not needed for the short runs.
I like your fourth battery idea which is why I looked. But thought about where you would have to put it for the cabling equalizing issues.
680 amp hours versus 900+ is no contest. I do not have a household refer but if I did the perfect four battery setup and 1000 watt solar will be my first step if I were to consider it.
