Battery Cable Sizing - PD9260
After working on friends trailer last week, one item that was not addressed was the size of the battery cabling, which I believe was a 6AWG (maybe an 8AWG, not sure) for his 2001 trailer, a 26 ft mode...

Instead of thinking the converter pushes think of the battery as pulling. The battery will "accept" a certain number of amps, where at any SOC, it will accept more amps if you raise the voltage. (That is why they use 14.4 instead of 13.6 so it will accept more amps)
At any chosen voltage, the battery will stop accepting that many amps when it gets to a certain SOC, so after that if voltage is held the same, amps must taper as "acceptance rate" declines as SOC continues to rise.
You can see it all here in my famous fantastic ugly graph, which I built after reading up on this stuff in Barre's book:
