Hey Ron, congrats on the brand new 5th wheel trailer. The Reese Sidewinder 5th Wheel King Pin with Rotating Turret item # RP34FR is what you'll need to replace a Rhino pin box.

What kind of 5th wheel hitch do you have? The item # RP34FR comes with a wedge that works with Reese and Pro Series hitches. You're going to want to get a wedge that's designed for your 5th wheel hitch.

@RonT The wedge prevents your 5th wheel trailer's king pin from rotating inside your 5th wheel hitch. If you didn't use the wedge your rotating pin box would rotate along with the king pin inside your hitch. What kind of 5th wheel hitch do you have?
