Recommended Custom Install Kit For 5th Wheel Rails On 2016 GMC 2500 And Gooseneck Adapter

Expert Reply:

For the easiest install on your 2016 GMC 2500 Denali, I recommend the Reese Quick-Install Custom Base Rails and Outboard Installation Kit for 5th Wheel Trailer Hitches # RP56001-53. These rails are 48 inches long and make it a little easier to install the rails to the custom brackets. If you want the traditional 43 inch length rails, the custom bracket kit I recommend for your truck is # RP50066-58. These kits come with all the hardware needed for installation. They require no drilling into the frame of your truck, but you will still need to drill into the bed to secure the rails to the bracket and the bed.

For a gooseneck ball to fit on these rails, I recommend the Curt Above-Bed Gooseneck Trailer Hitch for Fifth Wheel Rails - 3" Offset - 25,000 lbs # 16055 or the Reese Above-Bed Gooseneck Trailer Hitch - 25,000 lbs # RP58079.

You may also want to consider the Bargman 5th Wheel/Gooseneck 90-Degree Wiring Harness w/ 7-Pole Plug - GM, Ford, Ram, Toyota - 9' Long # 50-97-410. This will give you a second 7-way trailer connection in the bed of your truck for easy access and connection.
