Carrying 8000 lbs on the rear axle and 4500 lbs on the front axle of a F250 while towing an additional 8000 lbs on a 28" extension for over 30,000 miles without failure or accident even though many of those trips traversed the Rockies?
I had a good history with the 6.0 PSD for over 115k miles in 10 years towing all over the states west of the Mississippi River.
I occasionally locally towed, launched and recovered a 28' closed bow Bayliner (friend owned it but had no truck) with an 80's Mazda pickup. The same truck was frequently towing a 22' Challenger over mountain passes safely while only getting single digit mileage out of a 4-cylinder.
Is this what the OP is asking for?
