Question:

Hello, I have a 2019 3500 Ram Limited with Ram Boxes, I am looking to buy a Jayco Fifth wheel GVWR is 16750 and unloaded vehicle weight is 14035. I would prefer not to have rail in the bottom of the truck bed as I tend to like to maximize the flat surface. what would you recommend for this type of set up King Pin, Hitch Many thanks for your help

The only underbed fifth wheel install kit for a 2019 Ram 3500 is the Underbed Rail and Installation Kit for Demco Hijacker UMS 5th Wheel and Gooseneck Trailer Hitches part # DM8551006 which can then be used with the Hijacker UMS Double Pivot 5th Wheel Trailer Hitch part # DM8550032. The Demco Hijacker UMS is a great option which has a full wraparound style jaw that makes for an exceptional ride due to the reduced chucking and jarring.

Please note, because of the RamBox feature you must install a rotating pin box on the trailer so you have room to make turns without the pin box hitting the bed. For this, the Sidewinder 5th Wheel King Pin with Rotating Turret part # RP34FR is likely correct but you will need to confirm the model number on your specific pin box beforehand.
