Claim:
A trailer configured for articulated movement adjacent a tow vehicle and traveling in a generally forward direction when being pulled, comprising: an under-carriage having a trailer tongue, frame, suspension and running gear; a cargo box having a generally parallelepiped geometry extending longitudinally parallel to said trailer tongue, a leading surface most nearly adjacent said tow vehicle, and a trailing surface longitudinally distal thereto, said cargo box accessible from on a top side; a first side bag of generally parallelepiped geometry longitudinally shorter than said cargo box and placed laterally adjacent thereto, said first side bag having a leading surface which is displaced longitudinally rearward of said leading surface of said cargo box to effect an aerodynamic streamlining therebetween when said trailer is traveling in said generally forward direction; a second side bag of generally parallelepiped geometry longitudinally shorter than said cargo box and placed laterally adjacent thereto and opposed to said first side bag, said second side bag having a leading surface which is displaced longitudinally rearward of said leading surface of said cargo box to effect an aerodynamic streamlining therebetween when said trailer is traveling in said generally forward direction; a release for at least one of said first and second side bags adjacent said cargo box and actuated to open said at least one of said first and second side bags; a top cover having a generally rectangular leading member extending a lateral distance comparable to said cargo box which covers a forward portion of said cargo box top side when closed thereupon, and a trailing member extending a lateral distance greater than said cargo box which covers said release when said top cover is closed upon said cargo box; and a lock retaining said top cover in said closed position upon said cargo box.
