Will Trailair King Pin Work With Demco Fifth Wheel Rail Adapter on 2017 GMC Sierra 3500?

Question:

I have a 2017 GMC Sierra 3500 with factory puck set up. I had to get the adapter that goes into the goose neck hole. Can i use the Travel Air pin box to get a smoother ride. I dont want to go any higher on my height since Im around 13 feet 4 inches now. Also I was told you cant use it with an adapter.

I spoke with a representative of Lippert who told me that you can use a Trailair such as # LC369535 with the Demco 5th Wheel Rail Adapter # DM6194 that you have in your 2017 GMC Sierra 3500. The Demco Adapter mounts in your puck system and is not a gooseneck adapter, it gives you rails to mount your fifth wheel hitch so it will work for you.

To find the right Trailair you only need to know what model your current pin box is. The Trailair # LC369535, for example, is a replacement for Lippert 1621 5th-wheel pin boxes. I've added a link to each of our available Trailair units for you as well so you can find the correct one.
