Critique proposed solar battery upgrade
Currently have a Jayco hybrid (Jayfeather 26L) but moving to a Denali 5th wheel in the spring (2012 DE324LBS). Currently have 4 Trojan T125’s with 600 watts of solar, with a Kisae 2000 watt pure sine...

Once I knew that, I just use the Tri counter and know if I am only up to plus 5AH, I am not quite there. ( If you are in one spot like a stick house long enough, you can fiddle with the Tri setting for that so it comes out to full SG at the same time the Tri gets back up to zero.)

Since you already have a Bogart Trimetric, you could get the Bogart Solar PWM which ties in with the Trimetric and allows you terminate absorb on the basis of true battery charging amps or Amp Hrs. IOW automate what you're doing now.
My Rogue MPPT stops absorb on the basis of amps (or time) but doesn't know if those amps are going to the batteries or the loads. The Bogart system does.
But still, I would be careful about AGMs (other perhaps than that Outback nanocarbon or carbon foam) if partial state of charge is a frequent occurrence. At least with FLAs you can blast them with a high equalize charge when necessary to help de-sulphate.
