*Super Duty Chassis Cab does not offer a fifth-wheel hitch as a factory-installed option.

(1) Weights shown are for 141-inch wheelbase models. For 165-, 189- and 201-inch wheelbase models, weights may be somewhat less (usually 200 pounds with

165- and 189-inch wheelbase, or 400 pounds with 201-inch wheelbase). (2) Weights shown are for 176-inch wheelbase models. For 200-inch wheelbase models, weights

may be somewhat less (usually 200 pounds with F-350, or 100 pounds with F-450/F-550). (3) Available with High Capacity Trailer Tow Package only.

Note:

Trailer king pin weight should be 15-25% of total loaded trailer weight. Make sure vehicle payload (reduced by option weight) will accommodate trailer king pin

weight and weight of passengers and cargo added to the towing vehicle. Addition of trailer king pin weight, and weight of passengers and cargo cannot cause

vehicle weights to exceed rear GAWR or GVWR. These ratings can be found on the vehicle Safety Compliance Certification Label.
