Abstract

Cargo carry apparatus (20) for a tractor (500) for a semitrailer truck includes a rotatable deck (22) mounted between the fifth wheel (502) and the cab which pivots from a vertical position to a horizontal position until the deck rests upon the fifth wheel. With the deck in the horizontal position, the tractor may be utilized to transport cargo to sites which are inaccessible to the semitrailer truck. A variable length controller (32) such as a hydraulic cylinder is used to rotate the deck. The deck has slots (40) which accept stakes (42) to enclose the deck.
