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...

The MSW didn't matter with the Vector charger, but it would matter with the PD converter. That brand is known to need PSW where a WFCO does not ISTR.
I don't know how the truck's 12v system all works. I gather they have some variations in what you can do among different trucks. I described what happened in my case. My alternator is 105amps.
I figure the same sort of thing will happen with any version of that method, but the limiting factor amounts would be different. Same limiting factors though. Inverter limit and truck limit.
Only way to find out what yours will do is try it.
BTW it is no use running the inverter at just above its alarm off voltage for its input, when the truck won't run on that low a voltage. You have to keep the truck's voltage up to normal 14v. It (mine)doesn't sag down a little below 14 and stay there. Once it starts to sag it just keeps dropping like a collapse.
