We used an F550 to haul a 12,000 lb tractor on a triple axle gooseneck. Truck handled the load with ease even though it was near its rated GCWR. The trailer on the other hand did not. Broken rims, broken axle, ripped out anchor point, blown sidewalls, etc... Brakes and bearings had to rebuilt or replaced every year. Had the trailer push me through an intersection in the rain, plus a couple of close calls due to marginal braking. Class A required.
Replaced it with a 4400 IH, and a 20t tag. Class AZ required.
