There is a section in there about the power management... I think it will help in other situations besides just straight battery power; examples could be 30amp and want to run both ACs, or AC+microwave. Or, 15amp power and want to run 1 AC...

I forgot to mention, the Victron inverters already do that. No need for something extra.
They actually have a few different ways to configure it. Check out their PowerAssist and ESS documentation.
Ok, so does that mean you have eliminated the factory charger/converter?
But, I'm still not sure I get it... with the precision power management, it is replacing the entire output side of the power grid independently of any of the input sources. I think that it so that it can monitor all of the inputs by being in the middle? How would 1 or both of the Victron's monitor all of the outputs from all of the possible inputs?
(trying to wrap my head around it...)

Correct - my 48V Victron inverters have chargers as well, to charge the 48V bank. Then I have Victron Orion DC-DC converters charging my 12V battery, and supplying up to 60A of 12V load on their own. Or you could just go all 12V for a smaller system and eliminate the separate systems. The factory 12V converter is gone.
Everything passes through the Victron inverters. They are your power management. They have AC inputs (for shore power, generator, etc) and outputs for your loads. In a 50A configuration, you have two legs, each inverter physically handles one leg. If you use an autotransformer it gets a little complicated, but effectively it load balances the loads equally across both inverters, regardless of which leg the load is on.
If you have a 32A load and have shore power capped at 24A, for instance, the Victrons will supply the additional 8A via inverter/battery.
Not mine, but a nice schematic I found on another forum.
https://community.victronenergy.com/storage/attachments/6787-rv-inverter-design-end-state-victron-lifepo4-dual.jpgNote that the diagram has an autotransformer, but that is used to step up the generator from 120V to split phase 240V, and not to load balance, in this specific diagram. That's what my second unit does.
