I normally don't leave reviews, but this is worth the time and effort to do so. After multiple exhausting visits to the dealer regarding emissions-related problems, I came to Mr. Diesel for help. George personally took the time to explain exactly what was going on, how he needed to fix it, and assured me that I would never have any of those problems again. I trusted him. And he has yet to let me down. George Marcott goes above and beyond each and every visit and is always personally involved in the service/repairs. The kind of services he offers, the attitude he has with customers, and the knowledge he brings are top-notch. There isn't a better place in town to have normal service or serious repair work is done on your truck. Very highly recommended!!

These guys are the best! I took my truck in for a heater core. They did the work and the truck smelled like coolant bad and after the heater core replacement my thermostat was not working right. They had me bring it back and ended up doing a coolant flush and replacing the thermostat with no extra charge to me. I can't tell you how thankful I am that they did this after paying over $760 for the heater core! Really awesome guys and gals over there! They're my go-to repair shop now for sure!

Great shop. - Jo Ann M. (5 star review on Google)

These guys are phenomenal! Had them install a transfer case for me and an electrical clip break off after I left their shop. I went back and they found the problem and fixed it right away! Keep it up y'all! - Kevin J. (5 star review on Google)
