An aerodynamic, lightweight, flexible material flatbed top for enclosing a flatbed of a wheeled vehicle. The horizontal frame structure of front and side rails may be expansible. Inverted U-shaped cover support poles run front to rear and are mounted in the rectangular horizontal frame. A flexible material is stretched or draped over the support poles and secured to the frame structure. Cooperating locking and pivoting pin assemblies for each corner of the trailer top cooperate with corner brackets located at the deck corners of the flatbed to secure the top to the flatbed and to permit alternating rotation about an axis located at the front of the top or an axis located at the rear of the top to gain access into the space covered by the top on the flatbed.
