Unfortunate that some walk around with a chip on their shoulders these days just wanting to’prove others wrong’ and not willing to take them at their word.
For the record, i also have experienced much better pad mileage on my trucks than when I used to drive a Mustang convertible in the ‘80’s. My 2002 YukonXL 8.1 gasser was traded in in 2013 with 180k miles and original brakes (mostly city driving with work etc). My 2013 Duramax was traded in in 2022, again with about 180k miles and original brakes, this pulled a 15k 5er about a third of those miles or more including over the Rockies several times (it did have an exhaust brake which was always used when towing).
My 2022 F350 now has 26,000 miles on it, the majority towing a 16k 5er. Brakes are fine, but it sure seems to put more brake dust on the front wheels than I remember with the GMs, not sure I want these pads to last as long :)
FWIW, I drive ~63mph on the Interstate pulling, but frankly do 80%+ of my driving on highways on backroads.
