Our Truck & Trailer Repair Testimonials

Read what other clients had to say about us!
We broke down in San Antonio, with a loaded trailer and found Bull One Diesel repair. Bull, the owner is extremely knowledgeable and the technician that worked on our truck stayed late to get us back on the road. We highly recommend Bull One.
