This is the worst review that I have seen so far on the Titan diesel. I hope that it is an isolated case: http://www.caranddriver.com/reviews/2016-nissan-titan-xd-long-term-test-review
I am sorry, but I don't believe that a 1991 F250 4x4 crew cab pickup had a payload of 3,200 lbs. Maybe a bare bones regular cab 4x2 with a small gas engine, but not a crew cab 4x4 with a large gaser or diesel like the examples above.
