I was given one of the demco 6333, will the curt a20 slider fit onto the demco 6333? If not what other slider 5th wheels do?

Hey Darren, that's quite the gift. The Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package item # DM6333 will fit any 5th wheel hitch that attaches to industry standard rails, including the Curt A20 5th Wheel Trailer Hitch w/ S20 Slider item # C55DR.
The only exception to this is the B&W Patriot Slider item # BWRVK3270 because it sits too low and hits the adapter when sliding.
Please note that the Demco 5th Wheel Rail Adapter item # DM6333 only fits the GMC puck systems on the 2020 - Current Silverado and Sierras.
