Aerodynamically configured trailers are provided with a downwardly slanted top surface section positioned at the rear of the trailer. In use, the rearward cant or slope reduces the low-pressure region that trails the end of the trailer, thereby reducing pressure drag. Aerodynamically configured trailers are also provided that maintain standard cargo capacity in a first configuration, and can convert to a reduced cargo capacity in a second configuration. In some examples, a rear roll-up door of one or more configurations is provided to facilitate loading/unloading, etc.
