WARNING   WARNING:  You must use the heavy-duty drawbar pin supplied with your vehicle when using the heavy-duty hitch. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.

Note:   Vehicles with a heavy-duty hitch must use the drawbar pin stamped 21,000 LBS. You can obtain a replacement drawbar pin at your Ford dealer.
Note:   Make sure to take into consideration trailer frontal area. Do not exceed 60 feet2 (5.6 meters2) trailer frontal area for conventional trailers. Do not exceed 75 feet2 (6.9 meters2) trailer frontal area for 5th wheel and gooseneck trailers.
Note:   Exceeding this limitation may significantly reduce the performance of your towing vehicle. Selecting a trailer with a low aerodynamic drag and rounded front design helps optimize performance and fuel economy.
Note:   For high altitude operation, reduce the gross combined weight by 2% per 1000 feet (300 meters) starting at the 1000 foot (300 meter) elevation point.
Note:   Certain states require electric trailer brakes for trailers over a specified weight. Be sure to check state regulations for this specified weight. The maximum trailer weights listed may be limited to this specified weight, as your vehicle's electrical system may not include the wiring connector needed to use electric trailer brakes.
Your vehicle may tow a trailer provided the maximum trailer weight is less than or equal to the maximum trailer weight calculated using the formula following the chart.

Calculating the Maximum Loaded Trailer Weight for Your Vehicle
  1. Start with the gross combined weight rating for your vehicle model and axle ratio. See the previous chart.
  1. Subtract all of the following that apply to your vehicle:
  • Vehicle curb weight
  • Hitch hardware weight, such as a draw bar, ball, locks or weight distributing hardware
  • Driver weight
  • Passenger(s) weight
  • Payload, cargo and luggage weight
  • Aftermarket equipment weight.
This equals the maximum loaded trailer weight for this combination.
Note:   The trailer tongue load is considered part of the payload for your vehicle. Reduce the total payload by the final trailer tongue weight.
Note:   Consult an authorized dealer to determine the maximum trailer weight allowed for your vehicle if you are not sure.
For additional information on trailer weights, reference the RV & Trailer Towing Guide available at your authorized dealer, or online.
