5th Wheel Sliding Hitch Recommendation for 2015 Ram 3500 6-Foot Bed with Factory Rail Kit

Nice truck! I hope you enjoy your road trips.

We do not offer any auto-slider 5th wheel hitches but we do have many standard sliding hitch options from Pro Series, Reese and B&W. Even better, since your truck has the factory prep package you have the option to use a fixed hitch like B&W # BWRVK3600 along with a Sidewinder replacement pin box. This hitch fits right into your factory pucks. This type of set-up provides much better turning clearance than any slider. This is the case because a Sidewinder will move the trailer's pivot point back by 22-inches, which is about double the clearance gained from using a typical slider hitch.

Sidewinders are selected based on your trailer's current pin box brand and part number, which you can find on a sticker on the side of the pin box. With that information in hand you can use the linked article to see compatible Sidewinders that will bolt on in place of your standard pin box. For example, if you currently have a Lippert 1621HD pin box you can use the Reese # RP34FR which is a direct bolt-on replacement. Note that the highest-capacity Sidewinders we offer are rated for 20K, not 19.5K.

If you do happen to choose the excellent B&W hitch you can use a custom wedge # RP74FR which holds the pin box steady at the hitch so its rear turret becomes the pivot point.
