Abstract: A truck cap [12] has an upper panel [13], rear panels [15, 15'], and an articulated door [16]. The door [16] comprises an upper section [17] and a rear section [18] and is capable of movement between a closed position, partly opened positions exposing a rear opening [28], and a fully opened position exposing both rear and upper openings [28, 29]. Support ledges [25, 26] are mounted to the upper panel [13] to support the door [16] in its closed and partly opened positions. Securing elements [19, 20] secure the door [16] in its fully opened position.

Abstract: A truck is convertible between configurations as a panel truck and a pickup truck. It has a movable body section adapted to be positioned so as to shelter a rear portion of the truck cargo bay and so as to expose the rear portion to ambience. A fixed body section that shelters a forward portion of the cargo bay has a track mounted upon its top. The movable section has pivotable runners guided on the track.
