We do have a Sidewinder pin box that will replace the Leland 7921 you have on your 2006 Jayco with the part # ST400-5AS16K which is cushioned to improve ride quality. This will give you additional turning clearance and will allow you to not need to use the slider mechanism of your Patriot hitch.

Hey Jerry, GM moved the placement of their puck systems starting with 2020 models so you are correct that the pucks would have the hitch not sit directly over the axle. GM did the math and made sure that this placement wouldn't adversely affect…
