The MACK Granite Dump Truck by Bruder offers children realistic and active fun. This highly detailed truck features a realistic driver’s cabin with doors that open, adjustable side-view mirrors, a tilting engine hood which provides a full view of the engine block, and many other features which give these trucks their beautiful chrome look. Like a real dump truck, the open-box bed lifts at the front and tilts allowing the content within to be deposited. Bruder Mack Dump Truck Video.
