A truck body includes a rear wall, with the rear wall arranged to receive a plurality of "L" shaped air duct members, each including a first and second intercommunicating pneumatic conduit to direct air from side walls of the truck body to the rear wall to enhance cleaning of the rear wall of the truck minimizing separation of vacuum at a trailing surface of the truck to increasing resistance of a truck resulting in decreased fuel economy.
