Abstract: The pickup truck with drop-down side panels is a truck with side walls and a tailgate that may be raised and lowered to transform the truck between a pickup truck and a flatbed truck. The drop down left side panel, drop down right side panel, and drop down tailgate each comprise one or more height adjusters. An individual height adjuster may comprise a track gear coupled to the panel to be moved, a motor coupled to the chassis of the truck, and a drive gear coupled to the shaft of the motor. The teeth of the track gear mesh with the teeth of the drive gear such that rotation of the motor in a first diction lowers the panel to a down position and rotation of the motor in a second direction lifts the panel to an up position.
