A storage container for a tractor trailer. The storage container includes two side walls positioned parallel to two frame rails on the tractor trailer. Two end walls are coupled to the two side walls. A bottom plate is coupled adjacent the tractor trailer. A cover plate is hingedly coupled adjacent the tractor trailer. The storage container opens parallel to the two frame rails. A method for using a storage container includes remotely activating an actuator coupled to a cover plate, wherein the actuator causes the cover plate to rotate in an arc parallel to a frame rail on the tractor trailer from a closed to an open position; adding or removing items from a storage area; remotely activating the actuator, wherein the actuator causes the cover plate to close; and remotely locking the storage container.
