For a custom install/bracket kit that uses existing holes in the truck's frame which would be considerably easier to install, use # RP50081-58 for your 2013 Ford F-150 5-1/2 foot bed.

In order to gain the proper clearance between the rear of the truck cab and the front of the fifth wheel, a Sidewinder replacement pin box would need to be used because your truck bed is shorter than 6 feet. You would need a specific model Sidewinder to replace the OEM pin box on your fifth wheel. Your existing pin box should have a manufacturer name and model number on it somewhere. You would then match up that information to the listing shown on the Sidewinder FAQ article I have linked you to. I would recommend closely looking at the clearance formula shown on the FAQ page to determine if you will be able to negotiate 90 degree turns. For the A dimension, you will need to measure the distance from the jaws of the fifth wheel to the rear of the cab. When installed, the king pin would sit 1-1/2 inches forward of the rear axle center.
