Go read any head to head comparison or the the "King of the Hill" tests.
Ive towed a 10 thousand pound trailer with a 6.7, and it was effortless. ive also pulled the same trailer up a freeway exit ramp in the grass that was a 20% grade. not even sweating. also getting 16mpg average, which happens to be more than my 5.0 f150 2wd gets. Not to mention how many miles ahead ford is with their interiors! the new 14 interiors on GM products SUCK too.
