Stackable shipping containers are disclosed that can also act as trailers to be pulled by standard tractor trucks for travel over the road. Each of the stackable shipping trailers includes a substantially rectangularly shaped container having an interior capable of holding equipment or freight therein. The container is comprised essentially of two side walls, a front wall, a rear wall, a bottom wall and a top wall which form a substantially rectangularly shaped box having four top corners and four bottom corners. A standard corner casting is located in each of the corners. Extending rearwardly of said container is a frame supporting a pair of wheels that extend downwardly below the level of the bottom wall. A front support frame extends forwardly of the front wall and supports a downwardly facing pin and bearing plate that are adapted to be engaged by the fifth wheel of a tractor truck. As a result of this construction, one trailer can be stacked directly on top of another without interference by the wheels or bearing plate and pin. The two stacked trailers can be secured together by the use of the mating corner castings.
