For a cushioned pin box for your trailer that has a Lippert 1621HD I would actually recommend the Sidewinder with 5th Airborne part # RP61422. Not only does this have an air ride feature to reduce the chucking you are experience but also it is a Sidewinder which means that you no longer would have to use a slider hitch.

This pin box will give you the needed clearance to make tight turns without making you get out and go through the hassle of using the slider feature of your hitch. You would just need to leave the hitch in the forward most position.

Or, to even greater reduce the chucking you could go with a stationary hitch like the part # RP30928 that has a jaw system that holds the king pin tight which will greatly reduce chucking. If used with a sidewinder pin box you will also require part # RP44FR to prevent the king pin from pivoting in the jaws of your hitch.

Slider hitches in general have quite a bit of movement since they have more moving parts so a stationary hitch with an air ride Sidewinder would give you the ultimate towing experience.
