I have great news!

For your 2018 GMC Sierra 1500, I highly recommend going with the Underbed Rail and Installation Kit # DM8551008, which is compatible with the excellent Demco Hijacker Autoslide # DM8550022. The custom under bed rail kit is confirmed to fit your truck and allows for uninhibited use of the bed when the hitch is removed. The Demco Hijacker features a towing capacity of 18,000 pounds and will slide automatically as you drive to give you 14 inches of additional clearance when making tight turns with your 6-1/2 foot bed. The wraparound, single-piece jaw will also provide a secure connection and reduced rattle.

I have attached a short video demonstration on this system that you can also take a look at.
