Which Sidewinder 5th Airborne for Keystone Cougar for 2020 GMC Sierra 1500


I just sent in a order for a Demco Recon Gooseneck-to-5th Wheel Trailer Hitch part # DM8550045 for my 2020 GMC 1500 short bed truck. I am going to use tem Reese 5th Weel Airborne Sidewindern Air ride King Pi on my 5th wheel 26foot foot Keystone Cougar RV. What Reese Sidewinder King Pin 16K do I use and what Wedge do I use?


Helpful Expert Reply:

The Keystone Cougar Fifth Wheel should use a Lippert 1621 Pin Box so for a Sidewinder 5th Airborne you'd want the part # RP61422. With that said the Demco Recon part # DM8550045 can not be used with a Sidewinder since this attaches to a gooseneck ball and the Sidewinders require a hitch that attaches to the truck bed in four locations like the Reese # RP30047 which attaches to industry standard rails. For a custom rail kit that fits your 2020 GMC Sierra 1500 you could then use the part # C65KR.

The wedge you'd then need is the part # SWW-03.
