I think that my coach battery interconnect solenoid connects the chassis battery in direct parallel with the coach batteries, so there's nothing to protect the alternator (?) from getting really hit with high initial inrush charging current if I were to drop in Battle Born Li batteries, from what I read about them
I think your inrush argument doesn't hold water for several reasons.
1. my class c had an oem 60 fuse--so if inrush exceeded that, it would blow.
2. my class C had #8 wire for the oem charging path. That limits it to about 50 amps.
I did replace the OEM fuse with a 50 amp automatic circuit breaker. I also added a 2nd charging path with #8 wire, switchable solenoid, and automatic circuit breaker.
Anecdotally, my alternator is still OEM and I do push it hard--even so far as running the 1400 watt water heater via the inverter. I use a 1/3 duty cycle--20 minutes of heating and 40 minutes off. That lets me arrive at the boondocking site with hot water and lots of battery power.
There is an excellent article on inrush at the smartgauge site.
