Thanks for letting us help Tracy. To safely use your Demco Autoslide 5th Wheel Trailer Hitches # DM6077 with a Trailair Rota-Flex 5th Wheel Pin Box # LC328330 you will need to add Demco Autoslide Capture Plates for Trailair Rota-Flex and Lippert Road Armor Pin Boxes # DM6171. These will replace the existing capture plates on your Demco Autoslide and will prevent the king pin from pivoting inside your fifth wheel hitch. I will attach a screen shot from the instructions that details how these are installed.
Did you recently replace your 5th wheel hitch or swap out your pin box?

I had that same pin box on my fifth wheel. And like the expert mentioned I needed DM6171 To help capture my pin box.
