Sidewinder Pin Box to Replace a Lippert 1621 to Improve Turning Clearance with 5th Wheel Trailer

Question:

I have a 2010 Ford F-150, with biggest V8, 8’ bed, and heavy duty towing package. My trailer is a 2010, 32’ Crossroads Cruiser. Trailer weight is 8900 lbs. pin box is Lippert 1621. I cannot turn the trailer without the top of gooseneck where it attaches to the pin box more than about 40-45 degrees. If I do it hits the sidewalk of the truck. I would like to switch to a sidewinder hitch. Which model would you recommend? Thanks for your help. Jim

It sounds like your fifth wheel trailer's pin box is making contact with your 2010 Ford F-150's side rails when you make turns. This is one reason why we recommend at least 6 inches between the underside of the trailer and top of your bed rails. One solution to your problem is a taller fifth wheel hitch but this sometimes can cause your entire setup to not ride level. Another solution, like you suggest may be a Sidewinder pin box.

Sidewinders are designed to replace specific pin box models, and since you currently have a Lippert 1621 the correct one is part # RP34FR for the 20,000 pound model. Or if you'd prefer a Sidewinder that's also a cushioned pin box to improve the ride quality then use the Reese 5th Airborne Sidewinder, part # RP61422.
