And even now I'm thinking, hmm, how to automate that, only heat the water when bank is well on its way to full so only solar or alternator surplus production is being used. . .

Plus hydrometers.

Exactly. Used as a constantly connected Bank, then The Bank will not last as long.

As long as the weakest link.

Did you keep the SmartGauge hooked up to see to what degree SoC% matches?

Especially over time so get a variety of scenarios would be great.

Loads may be "diverting" most of that, or even depleting the bank while the charge source is running.
