Today’s “McDevitt Trucks” is the result of nearly five decades of continuous efforts to respond and adapt to New England’s transportation needs. Established in 1974 by Jack McDevitt, Sr. and his five sons as “Manchester Mack Sales,” the company was renamed as McDevitt Trucks in 2000. It’s now an authorized dealer for Mack, Western Star, and Isuzu Trucks in Manchester and Lancaster, New Hampshire.

After having operated multiple facilities in New Hampshire, Massachusetts, and Vermont from 2000 through 2018 under the “McDevitt Trucks” and “Patriot Freightliner, Western Star” brands, McDevitt Trucks joined the Advantage Truck Network (ATG) in late 2018. The Manchester and Lancaster operations continue to operate as McDevitt Trucks, while all other locations operate as ATG.

McDevitt Trucks and ATG are committed to a relationship-based customer support environment. Many of the companies’ customers have relied on us for 30 years and longer because of the partnership approach taken by all employees in all departments. Whether it’s sales, parts, or service, customers can expect a consistent, professional, and respectful experience at all McDevitt Trucks and ATG locations.
