For the redesigned 2019-2026 Ram 1500 with the 5'7" box (67.4"), no RamBox and a standard drop-down tailgate, this is the Sentry CT. It is not compatible with the multifunction tailgate, and on a TRX the factory bed bar must come off. It is a hard roll-up cover: aluminum slats lock together beneath a patented RTxTechWeave canvas, and the whole cover rolls up against the cab for full bed access. Lock the tailgate, if yours has a key lock, and the cover is locked too. Closed and latched, it carries 400 lb of evenly distributed weight. On most trucks it goes on with clamps alone, no drilling. It carries TruXedo's 5-year limited warranty.
