The Mack MC/MR series, also known as the "Cruise-Hauler", is a cabover truck first introduced in 1978.[1] It is of a distinct "set back front axle" design (first seen on the Mack FM), with the driver compartment mounted ahead of the front axle and with a large, flat, divided windscreen covering almost half of the truck's frontal aspect. The chassis were very common for fire apparatus.
Design
The MC/MR was designed from the beginning to be available in right-hand drive as well as left-hand drive.[1] This allowed Mack to market the truck in the United Kingdom without costly conversions, and also opened the trash truck market at home. The right-hand drive models also have the exhaust relocated to the left, while the turbocharger is mounted behind the engine so as to provide more space and less heat soak.[1] Export models are coded MCE and MRE respectively. The low profile cab is of steel, while the doors are fibreglass. The engine intrudes considerably into the low cab. The cab tilts through a full 90 degrees, allowing for the radiator to be removed without first removing the cab.[2] The dashboard is lit from a single source through fibreoptics, this being a very early example of such an application.[2]
