Testimonial:

 
I wanted to call and tell Doug that my truck is working great after he worked on the computer, I went to Freightliner and they told me that was the best they could do so I came to Southwest Diesel and now I am so happy my truck runs great. I use to be a mechanic and I like to make sure I call and let people know when they do a good job.
