That would have been the 1st-gen GM, Chevy S-10 / GMC S-15, circa 1984- 1991. They were around Cd 0.475, naked, as a pickup, and as low as Cd 0.315, and 211-mph, with the aero modifications made to the Gale Banks Bonneville LSR race truck, circa 1991.
A 'level' bed cap would have helped. The one depicted is adding frontal area, so it would be cutting into the drag reduction. Maybe break even.
