What's interesting about the GM fifth wheel rail kits in the 2018 GMC Sierra 3500 is that the pucks are different widths apart based on the length of the truck bed. So the Demco 5th Wheel Rail Adapter part # DM6194 fits the short bed trucks and then for the long bed trucks you'd want the Demco 5th Wheel Rail Adapter part # DM6206.
