I believed the exact same thing until I bought my current truck. All of a sudden, even though I did the same thing to the charging system that I had done on two previous trucks, using higher gauge wires than I used on either of the two, it couldn’t keep up with the draw from running the fridge in AC mode while driving, and we were arriving at our destination with a severely depleted battery. That just won’t work for us.

You are not giving specifics, so hard to figure out what you are talking about.
I had undercharged batteries with my 2017 F350 as well, even truck had dual alternators. Even I did not used power for fridge, the deeply discharged batteries did not recharge in 3-4hr drive like they used in the past. I figured out the new truck has more sensitive circuit breaker on charging circuit, who was trickling with more time off, than on and that did not give enough charge. Had the same phenomena with 40 amp converter who would not charge much in 3 hr of generator running.
So do you have lead-acid batteries and use B2B charger for them? What voltage you set?
When I am not electrician, my experience is that any charging voltage over 14V will shorten battery life.
Kayteg, go read what you wrote. You’re firmly contradicting yourself and contradicting known facts to try to prove I’m not sure what. Other than arguing against a DC/DC Charger while confirming that your truck does a poor job of charging house batteries on its own!
