IDEA...charging house battery(set) underway.
It seems that the chassis alternator/VR system will often not fully charge the house battery(set) due to voltage drop between the two, or overcharge, boil the electrolyte away, for a deeply discharged...

I'll not be searching.
Alternator output is limited by RPM, the cabling, the voltage regulator and the batteries themselves.
So much so that alternator undercharging is way more of an issue than overcharging, in my opinion.
When my batteries are low, I'll expose them to everything my charging sources can feed them to get them to as high a state of charge as possible before the next discharge cycle begins. My alternator can't make 92 amps for very long, nor will the batteries accept that much for very long before the voltage would rise to the point the VR would throttle back the alternator to only what was needed to hold that regulated voltage.
I'd adopt the chassis battery powering the inverter powering a converter to charge the house batteries only to help keep them at Absorption voltages longer than my current voltage regulator allows.
Or perhaps If I had a AGM bank that would be destroyed by the 14.9v my VR allows.
