That kinda sucks about the trip limit. My early '22 limited Trip-2 has never been reset, so it matches the truck's lifespan within a mile.
I think i'm around 16mpg with 17,000 miles but i've easily done 4,000 of that towing heavy enclosed trailers and car haulers. Also lots of 80-85mph on cruise control which kills the MPG compared to 70/75. I'll usually get 20-21mpg on smaller state roads doing 55-70.
