This is a bed cover, and it is usually used in real life to keep loose materials from falling out and causing damage. This one is a hardcover instead of a canvas top, to work as insulation to keep the cargo a bit less cold. It also has a slot for the hook on the crane to keep it from swinging around. #thecheese #beesebrickbuilds
