Underbed 5th Wheel and Gooseneck Hitch for a 2018 GMC Sierra 2500

Question:

I have a 2018 Siera 2500 HD. I made the mistake of not getting the Factory Z6A option that installs the under bed mount for 5th Wheel/Gooseneck. I have a 4400 Superglide Pullrite 5th wheel hitch. What i would like to do is install an under bed kit that does both configurations and i could adapt my Superglide to it. I fully understand that the Option is a puck system. I am willing to design and fabricate my own adapter to the puck system. My question is: I cant find a gooseneck and 5th wheel kit that is similar to the option Z6A. Would you have one?

There are underbed 5th wheel/gooseneck install kits for the 2018 GMC Sierra 2500 though they are not exactly the same as the factory one which is made by Curt.

You can use B&W hitch # BWGNRK1016-5W and then add the Companion Slider # BWRVK3400-5W for a short bed or the regular Companion # BWRVK3500-5W for long bed models. For this set up though there isn't an adapter that would work with your 4400 SuperGlide hitch. But you could find a buyer for the SuperGlide to offset the cost of the B&W set up.

I can't say whether or not there is a safe way to add mounts for the SuperGlide so that would be an at-your-own-risk type of situation.
