Providing Expert & Honest Service For Over 40 Years

It all began with a MA Dairy Farm!

State Line Truck Service was incorporated in 1975 by Kendall “Gus” Crocker. Gus started State Line originally when he purchased the property in Fitzwilliam, NH to build a shop for KF Crocker Transportation. KF Crocker Transportation hauled milk and liquid food products throughout New England. KF Crocker was originally started in Ashby, MA by Gus’s father because the dairy farm they lived on was on a big hill, far too out of the way to pick up milk.

Family owned and operated

When the land was purchased in Fitzwilliam, people driving by would stop to see if they could purchase parts or if they could get help with servicing their trucks. From there the idea for State Line Truck Service evolved. State Line then became an authorized service dealer by Manchester Mack, which is now McDevitt Trucks, Inc. Gus’s wife, Linda came on board in 1978 running the office with no computers! She was actively involved as Treasurer until her passing in 2017.

Decades of experience – Unsurpassed Customer Service

Today, over 40 years later, State Line Truck Service is still a family owned and operated business. Kelly, Gus and Linda’s daughter, joined the company in 1994 and purchased in 2007. Her daughter, Emily Stauffeneker, joined in 2014 along with her daughter in law, Keri Coll in 2015.
