The upper mounting assembly for the long-travel rear shocks is welded to the frame and travels through the cargo floor of the Jimmy. This upper mounting assembly also serves as the mounting location for the rear shock reservoirs. The assembly is made from 1.75-inch-diameter, 0.120-inch-wall tubing. The rear cargo area also holds a Contico storage box, cooler, 4,500 psi air tank, and a spare wheel and tire. The cargo area has been coated with two coats of Herculiner, two coats of Dupli-Color Bed Armor, and a rubber pickup truck mat has been sized to fit under the spare tire.
