Tongue weight refers to the downward force exerted on the hitch ball by the trailer coupler. It's an important factor in towing safety as it affects the stability and handling of the tow vehicle and trailer combination.

To calculate tongue weight:

1. Determine the percentage of tongue weight: Generally, tongue weight should be about 10-15% of the trailer's total loaded weight. However, this percentage can vary depending on factors like trailer design, load distribution, and towing conditions. (Do not exceed max tongue weight of vehicle and hitch listed in Ford Owner Manual).
   
   
2. Measure the trailer's loaded weight: Fully load the trailer as it would be for towing, including all cargo, gear, and fluids. Use a vehicle scale or specialized trailer tongue weight scale to accurately measure the trailer's total weight.
   
   
3. Measure the tongue weight: If the tongue load is greater than max rating re-adjust trailer load to get tongue load with in rating and within 10-15% (Conventional) 15-25% (5th Wheel & Gooseneck) of trailer weight.
   
   
4. If the vehicle is equipped with Onboard Scales, you can measure the Trailer Tongue Load. For those vehicles that are not equipped with onboard scales, we recommend visiting a weight station or public scale at a truck stop.
