5th Wheel Hitch And Rail Recommendation For A 2021 GMC Sierra 2500 HD


I am getting a 2021 GMC 2500 HD truck soon and I need a fifth wheel sliding hitch. I have a standard bed and need to know what hitch will work? Do I need the adapter rail?


Expert Reply:

For your 2021 GMC Sierra 2500 HD I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - Single Jaw - Above Bed - 21,000lbs Item # DM8550035 and the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 21K item # DM6333.

This hitch will offer you the highest GTW at 21,000lbs and the longest slider travel at 14 Inch Fore/Aft Travel. You will need the rails to attach this hitch to your 2021 GMC Sierra 2500 HD.
