A pair of integrated ramps attach to the rear of a trailer or utility cargo bed, the ramps swinging on a horizontal plane from a stored position and then being rotated to form a pair or flat ramps surfaces in a flat position, the ramps sliding along the rear end of a trailer on a secure end railing. The sliding railing provides adjustment to the width of the ramps for the purpose of off loading cargo carried upon the cargo surface of the trailer, the ramps forming a stable angled surface between the cargo bed and the ground. The ramps may form a tailgate in a stored position or be made part of the side rails for the trailer in the stored position.
