Take your trailer measurements.

• Ensure your tow vehicle and trailer are on flat, even ground over the full length of the truck and trailer (It may help to tow your trailer to a nearby parking lot for more accurate measurements).
• Measure the number of inches from the top of the trailer coupler to the parking surface as the diagram to the right shows. Enter this number in the coupler field.
• Measure the number of inches from the parking surface to the inside-top of the 2" square receiver box. Enter this number below in the receiver field.

The pictures below show where to take the measurements needed to determine which hitch bar is best for your truck and trailer.
