1.5:1 Scale USPS Postal Service Mack MR Trucks & Trailers

The Mack MC/MR series started in 1978 and later upgraded to the TerraPro series, also known as the "Cruise-Hauler", a cabover truck. 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. The MC/MR was designed from the beginning to be available in right-hand drive as well as left-hand drive. 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.

The United States Postal Service (USPS; also known as the Post Office, U.S. Mail, or Postal Service) is an independent agency of the executive branch of the United States Federal government responsible for providing postal service in the United States, including its insular areas and associated states.
The USPS as of 2017 has 644,124 active employees and operated 211,264 vehicles. The USPS is the operator of the largest civilian vehicle fleet in the world. The USPS is legally obligated to serve all Americans, regardless of geography, at uniform price and quality. The USPS has exclusive access to letter boxes marked "U.S. Mail" and personal letterboxes in the United States, but now has to compete against private package delivery services, such as United Parcel Service and FedEx.
