Texas Diesel Company is 28 miles west of Bonham — about a 38-minute drive to our shop in Van Alstyne. Bonham is on the eastern edge of our regular service area, and while the drive is longer than for closer cities, we serve a steady base of Bonham customers for diesel work that’s hard to get done locally.
Why Bonham residents come to us
Bonham and Fannin County have a strong agricultural and ranching base, and the diesel pickup is the working vehicle of choice for most of the area. What’s missing locally is a specialized diesel shop with full Ford / GM / Dodge OEM factory diagnostic capability. Most Bonham customers who come to us have either tried the local general repair options first or have been driving south to Dallas-area dealers and decided that the trade-off of a 38-minute drive west is worth it for shorter wait times and real diesel specialization.
The shop’s reputation in Fannin County is built on word-of-mouth from owners who got the right diagnosis on the first visit. We don’t run flashy advertising; we keep customers by being straight and getting the work right.
Who we serve in Bonham
- Agriculture — farms across Fannin County running diesel pickups, tractors with diesel auxiliary equipment, and grain haulers
- Ranching — cattle operations and the working trucks that support them
- Small fleet operators — local businesses, contractors, and trades with diesel service trucks
- Fannin County government and municipal operations — diesel work trucks supporting local government services
- Daily-driver owners — Bonham residents whose diesel is the primary household vehicle
- Project truck owners — Bonham has plenty of diesel enthusiasts and we see good build work from the area
