Abstract
Abstract A loading apparatus for pickup trucks and the like is characterized by elongated interchangeable ramp sections releasably secured to the rear end of a special platform on the bed of the pickup truck so that the ramp sections are releasably attachable for downward extension from the platform to the ground, and further are slidable into a storage position beneath the platform when not in use. Alternate types of platforms have been devised to vary the effective width of the pickup truck bed to accommodate one or more vehicles, and the ramp sections include different types of tread surfaces which are interchangeable to facilitate loading and unloading of different types of vehicles.
