The adjustable load-carrying apparatus is designed for mounting on the load-carrying bed of a vehicle. It includes a base frame assembly which is fixed rigidly to the vehicle bed and has laterally spaced inwardly facing rollers in longitudinal alignment along each side edge thereof plus an inward lock guide rail. A slidable platform frame assembly has lateral trackways slidably mated with the rollers of the base frame. The platform frame assembly includes a lock guide structure on its underside in cooperative relationship with a lock guide rail of the base frame assembly. Additionally, the platform assembly includes on its underside laterally spaced ramp slideways. A ramp assembly is carried for sliding movement in the ramp slideways. It includes a ramp deck as well as a forward guide section and a hinge connection between the deck and the forward guide section whereby the ramp deck may be lowered for ramp use while a foundation portion of the forward guide section remains in the ramp slideways of the slidable frame assembly.
