Abstract: According to the present invention, a truck includes a truck body, a partition, a door, a first conveyor system and a second conveyor system. The partition divides the interior volume of the truck body into a first cargo volume and a second cargo volume. The door is located at the rear wall of the truck body and is selectively movable between an open position and a closed position. The first conveyor system is disposed in the first cargo volume and the second conveyor system is disposed in the second cargo volume. The first and second conveyor systems are separately and selectively operable to move materials in the first and second cargo volumes, respectively, towards the door. Therefore, the truck body of the present invention can carry two (2) separate loads of different materials using a single truck in a single trip.
