So I wanted to follow-up. Received the USB-Meterbus adapter today and gave it a try. It was very easy to setup the software and you have access to literally every setting via MSView. I was able to match exactly the charging setpoints of the Sunsaver MPPT controller to the Trojan T-105s.
At the end of the day I have no way of really telling how much benefit this will bring (just geeking out here really), but its kind of cool to know you can match up your system to the exact specs of your chosen batteries. Just need to get it out for some spring dry camping now :)
Thx for all the help.
