Cboyce, sorry this is months behind! Haven't been on in a long while. I have a 2018 28.5RSTS and and trying to to do the same thing you are. I have researched and came to the decision that the GenY was the way to go. Then I got the BAD news...LCI and my local dealer both tell me that, 2018-2019 only, Jayco tried an "experiment" with the wing rails that all pin boxes bolt to...they got away from the industry standard #1621 bolt pattern and tried a variation called #1622. It was available only in their Turning Point brand or in the upgraded Moryde pinbox. Their goal was to create an orbital hitch for the short-bed and 1/2 ton market. It seems everyone just locked out the orbital option and continued using it like a standard hitch so they abandoned the #1622.
I've learned that NO OTHER brands of pinbox will bolt up to this stupid wing system they tried so our options are very limited!
I was here trying to get advice from anyone on what traditional 5th wheel plate I should use to get away from the Anderson Ultimate I've had for 3 years. I have had no luck but I hope any meager information I can provide you may prove useful
Best of luck if you haven't already solved your problem!
