State Line Truck Service

State Line Truck Service State Line Truck Service is one of the most experienced truck service dealers in New England. From there the idea for State Line Truck Service evolved.

Our family owned and operated business has been servicing and selling parts since 1975. 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 ori

ginally 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. 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. 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 is still actively involved as Treasurer. Decades of experience - Unsurpassed Customer Service

Today, 35 years later, State Line Truck Service is still a family owned and operated business. Gus’s daughter Kelly joined the company in 1994 and now manages the daily operations. State Line offers all types of repair services including laser alignments and computer diagnostics. They also sell parts for most makes and models. State Line Truck Service is one of the most experienced Service and Parts Dealers in New England.

We are so sad to hear about the passing of not only a favorite customer of ours, but a real friend, Jon Flagg. We were always glad to see him come through the door and we will miss him immensely. We were thrilled he got to join us at our 50th Anniversary party back in October, and he was so happy to be there greeting many familiar faces. He had been a part of our State Line Family for many years and will be forever missed.

Hugs and prayers to Diane Flagg and their family and friends.

Merry Christmas to all! 🎄
