If you are looking for great prices and the best service for your diesel truck in San Antonio, then look no further than Tri County! I came in for a pre purchase inspection. Where as other places charge $300 - $400 for just one inspection, I got two separate trucks inspected here for half that cost. The two individuals I worked with, Michelle and Randy, were both very kind and professional.

My dad has been coming here for years to get his 18 wheeler fixed. Truman has always been so good to our family. Michelle, the office assistant is really great and so nice! We will continue to come here for diesel service. ❤️

What would have been a logistical nightmare at the dealership ended up becoming a great experience here.

I am very pleased with service I received from Tri-County Diesel Services. They replaced a carrier bearing on my 2016 Freightliner Cascadia, and got me back out on road with my load the next day. Charges for work were very reasonable. Michelle in the office was super! Very friendly and professional. I even met the owner, Truman, while waiting in the break room for my truck the morning after I left truck off for repair. Truman and I had a nice chat, I was impressed with him and his shop. I will definitely take my truck to Tri... read more
