A double drop trailer has a central storage or cargo section whose floor is at a lower level than the floors of the front and rear storage (cargo) sections. A first lift having upper and lower cargo platforms is located in the central cargo section, and a second lift is located in the rear section. The first lift is initially positioned so that its lower platform is level with the floor of the front section. Cargo is then moved through the rear door, through the rear section, across the lower storage platform of the first lift and placed on the floor of the front section. More cargo is then moved through the rear door and placed on the lower storage platform of the first lift. The first lift is then lowered. Additional cargo is then moved through the rear door onto the second lift and this lift is thereafter raised permitting this cargo to be placed on the upper storage platform of the lift. Finally, more cargo is moved through the rear door and loaded into the rear section of the trailer.
