Huntsman, I pull a 24’ stock trailer loaded with calf’s, probably about 18 head avg. @ 575# a piece, trailer weighs 6,500 empty with a 3/4 ton 6.2 flatbed and cake box on truck, 60 miles to SaleBarn and a lot of hills, it does OK . I prefer my Dodge Diesel by far with deleted 6.7, by my Ford 6.2 will do the job, guys with new 7.3 say you can’t even tell you have a load behind ya, and they were all 6.2 Ford guys.
