In 1930, Roy Gilbert Sr. started Gilbert Truck Line in Cotulla, TX with one used truck serving San Antonio, TX to Cotulla, TX. During 1940, He was able to secure authority to serve Laredo and the Mexican border. Through the 1940’s, the fleet grew to about 50 pieces of equipment. In 1950, Mr. Gilbert purchased Southwestern Motor Transport Inc., and merged the two companies. This brought the fleet to just over 100 units.

Currently, we serve most of the U.S.A. in truckload and LTL. We also perform thru service between Mexico, Canada, and the United States with over 350 tractors.
