Step 1

Know your weight

Know the total weight of the trailer (GTW) you are towing and the maximum towing capacity determined by the vehicle manufacturer. Next, select the correct class hitch, ball mount and ball for the job. WARNING! Do not exceed the maximum towing capacity of your tow vehicle.


* CLASS III is the most common hitch type among full size trucks and SUVs

Step 2
Level towing

For safe and comfortable towing, the trailer should always be as level as possible. A level trailer will put less strain on the connection between the trailer and hitch. It will also help the trailer stay in line behind the vehicle.

To determine the correct ball mount:

  • Measure the coupler height from the ground to the bottom of the trailer’s coupler (A)
  • Measure the hitch height from the ground to the top of the receiver opening (B)
  • Calculate the difference between the hitch height and the coupler height. (A minus B)
  • DROP is required if the hitch height is greater than the trailer height
  • RISE is required if the hitch height is less than the trailer height
Determine Drop
C = B – A | C = Drop
Determine Rise
C = A – B | C = Rise
