Abstract: A convertible pickup truck has the lower cab portion and a bed portion with a convertible cab top pivotally mounted on the lower cab portion which is movable between a raised position covering the lower cab portion and a stored position within the bed behind the front wall of the bed. The cab top is releasably secured to the windshield frame in the raised position and has a roof portion extending from the windshield rearwardly and downwardly over the lower cab portion and is pivotally attached to the rear wall of the lower cab portion. Latch members at the rear portion of the cab top and the lower cab portion releasably secure the cab top to the lower cab portion in the raised position. Resilient seals between the lower cab portion, the cab top, and the windshield form a weather-tight seal between the abutting surfaces of the members in the raised position.
