The cover assembly comprises a flexible top cover sub- stantially co-extensive with the body cross-section viewed from above and the cover extends across and is attached to a front wall of the body above the side walls with side skirts laterally clos- ing the area adjacent front and side wall junctions. A take-up roll for the flexible cover has a spring bias for rotation in a take-up direction and is mounted on a pair of arms at upper end portions of the latter. Lower end portions of the arms are pivotally attached externally at sides of the truck body for swinging the take-up roll through an arc in a lengthwise traverse of the truck body. In one embodiment a hand crank and cable sys- tem swings the arms in a direction opposite the spring biased take-up. -1-
