The U.S. Postal Service has ordered 2,000 fleet vehicles from Spartan Motors on a $214 million contract for two types of delivery trucks with Utilimaster bodies, the vehicle manufacturer announced.

The Charlotte, Mich.-based company's Spartan Fleet Vehicles and Services business unit will begin building the trucks after April 1. They will be delivered over the next two years. The contract includes an option for a third year.

The order includes a combination of cab-over-engine and straight trucks in a variety of 18-foot and 24-foot configurations. The cabover will likely be built on a Class 7 chassis.

"Our ability to design, custom engineer, and build commercial trucks across Classes 1-6, in addition to providing custom vocation-specific upfits uniquely positions us to serve the growing last mile delivery fleet that is in demand by today’s ecommerce retailers," said Tom Ninneman, president of Spartan Fleet Vehicles and Services.

The USPS is also developing its next-generation residential delivery vehicle. In September of 2016, the USPS awarded $37.4 million in contracts to six vendors to provide prototypes.
