Abstract: A truck box assembly including a sidewall, a pair of doors, and a support assembly is provided. The sidewall may define an opening to provide clearance for a wheel house. Each of the pair of doors extends from one side of the opening. The support assembly may be mounted to a truck box and support the sidewall as the sidewall moves between retracted and expanded positions. Each of the doors may be moveable between an open position and a closed position filling the opening in the expanded position. The support assembly may include a mount post secured to the truck box at a standard interface plate (SIP) bracket and a horizontal member extending from the mount post and secured to the truck box at a stake pocket hole.

Abstract: A leak resistant battery manifold vent for a battery. The battery manifold vent includes a vent housing having an interior volume, at least two cell vents, and at least one atmospheric vent. The interior volume comprises a labyrinth system, fluid collection chamber, and vent collar. The labyrinth system has at least two fluid passageways coupling the cell vents and the atmospheric vent. The passageways include more than one fluid baffle. A fluid baffle causes a constriction of the fluid passageway extends from only one of a top portion and a bottom portion of the vent housing. The passageway is coupled by a crossover vent providing fluid communication between the two passageways. A fluid collection chamber is fluidly coupled to the passageways. The chamber has at least two orthogonal dimensions which are larger than two corresponding dimensions of the passageway. A vent collar causes a constriction adjacent the cell vent.
