Measuring Your Truck and Trailer for the Ranch Hitch Coupler Adapter
You can perform these steps to determine if the adapter will work for your fifth-wheel trailer.
- Back your truck into position as if you were hooking up your fifth-wheel trailer, making sure that the truck and trailer are level.
- Measure from the pin plate (the bottom of the pin box) down to the top of the ball in the bed of your truck.
- The measurement should fall between 11-3/4" and 14-3/4". (The adapter is 11-3/4" tall when fully compressed and 14-3/4" tall when fully extended.)
Additional Measurements
Five or six inches of clearance between the overhang of the trailer and siderails of your truck is necessary for safe operation.

Measuring for Pin Box Length
The Ranch Hitch adapter is designed for trailers with a standard or extended pin box up to 24" long (measured diagonally). To find this dimension, you should measure from the centerline of the bottom of the king pin into the back of the pin box as far as you can reach. You may not be able to reach the very back of the pin box itself because the top of it may extend into the trailer. In this case measure to where the pin box disappears into the trailer.
