The Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit for 5th Wheel Hitches # DM8552034-71 has not yet been tested on the long bed of the 2019 GMC 1500 to confirm fit. Most of the time the frames are the same for those bracket fits, but they can't officially confirm until they have tested it.

I checked around with other manufacturers and Reese confirms the fit of the Outboard rail brackets kit # RP56015-53 for all the bed lengths including the long bed. This would utilize the existing holes in the frame, but will be an easier installation for both the brackets and the rails due to the longer rail length and outboard brackets allowing for more working space. I've attached some review videos to assist.
