Couple of questions about DC-Dc charging
I've been thinking about adding a DC-DC charger now that I've added 400 amp hours of AGM batteries. There are lots of useful posts but I haven't run into a couple of things I'm curious about. One ...

Please describe to me how multi-stage charging benefits a battery bank on a very very long 10-hour vacation driving day?
Stick to the program: A high amperage integral voltage regulated alternator. An ECU charging unit is a totally different animal.
Specifically *current limiting* is the objective to safeguard the alternator.
1. PROTOCOL A) A specified length of cross-link insulated tin plated fusible link wire
PROTOCOL B) A specified current limiting D.C. to D.C. controller.
Some hints: The current limiting wire is copper. Terminations can be soldered. It's routing is from the alternator or high amperage junction to (preferably) an automatic charging solenoid like a Blue Seas or Sure Power bi-directional charging solenoid that allows reverse direction charging from house to chassis battery. Remember the circuit is 100% automatic.
Or route a huge lead cable to say an 80-ampere D.C. to D.C. converter.
Here you can list perceived advantages. Take in consideration fusing protection and reverse circuit chassis battery charging.
Option A) Uses $15 fusible link wire and an $80 smart solenoid
Option B) Uses a converter, an overload protector circuit and whichever way to reverse charge the chassis battery.
Thank You
