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...

To evaluate the wiring upgrade option, he must decide if the generator time saved is worth the trouble of doing the wiring change.
Let's say he gets 35 amps at 14.4 now, and that with a wiring upgrade he will get 55 amps at 14.4. Time to do a 50-90 on two batts (220AH bank) goes from 3 hrs now to 2.5 hrs.
How many 50-90s does he do a week for how many weeks? How is the solar doing?
If he takes advantage of the generator running to also do some other chores that need 120v, then he might not get any benefit from an upgrade in the wiring. We don't know his camping routines.
With the converter running at full amps at first, he would have to wait until amps taper somewhat to get enough "room" to run his other things. If those other things take an hour and he can't start until hour 2, then the gen time will be three hours anyway.
Whatever, he is the only one who can say what would be worth it to him.
