A cargo loading and unloading system for use with a utility vehicle having a bed includes a movable sled for retaining cargo items, a platform mountable to the bed of the utility vehicle for receiving thereon the sled, a ramp for receiving thereover the sled and for facilitating the moving the sled up onto and down from the platform, and a flexible mechanism interconnecting the platform and the sled for controlling the movement of the sled between the ground and the bed of the utility vehicle. The sled has a base, wheels for moving the sled on a support surface and a pair of spaced apart inner longitudinal members which are disposed between the opposite sides of the base. The platform includes a base and a pair of guide rollers disposed above and mounted to the end of the base at the rear end of the utility vehicle bed. The guide rollers mesh with the inner longitudinal members of the sled for the purpose of guiding the sled between the ramp and the platform. The ramp contacts the ground at one end to support the ramp in an inclined orientation such that a second end is engaged with the platform at the rear end of the bed.
