Abstract: A trailer deck system includes a housing that includes a bottom wall, a top wall and a perimeter wall extending between the top and bottom walls. The perimeter wall includes at least one door to access an interior of the housing. The perimeter wall includes a lateral wall. A panel has a rear edge, a front edge, a first side edge, a second side edge, a top side and a bottom side. The rear edge is hingedly coupled to the perimeter wall to allow the panel to be moved between a stored position vertically orientated with the top side facing the lateral wall and an extended position extending outwardly from the lateral wall and is horizontally orientated. A motor assembly is mechanically coupled to the panel. The motor assembly moves the panel to the extended position or the stored position when the motor assembly is actuated.
