"The mechanic saved me time and money. I had repairs done at the truck stop incorrectly, left there and went to a repair shop down the road to fix the problem without luck. Return to the truck stop with my truck in limp mode and stop engine due to improper repairs. Called the Fleet Dr hoping to get somebody who knew what they were doing. He assured me he would fix the problem. Made me feel comfortable and knowledgeable about working on a Cummins isx. And had the right equipment to due the job correctly. Thanks again for getting me back rolling. Good honest mechanics are hard to find."
Jermaine Daniels
"All other road services that came out to me especially J&J Mobile unit SAD . All they wanted was road call money and was happy to say your going to have to get towed. This guy actually did the problem and fixed it .So anyone out there having trouble with their Semi give this guy a call. Not only cause I have a volvo but any truck. This guy is good I was backing the road same day."

L Bell
"I’d never call on anyone else for mobile repair or repair at his yard besides Fleet Doctor anywhere even remotely around Knoxville and this half of Tennessee. My new Great Dane trailer came without power plug in, in the rear, for my oversize amber light and he wired power to the back and mounted it perfectly near the license plate. Very competent and knowledgeable! He helped me out and I went to his yard and he did it for me right here on a Sunday. You read that correctly!" Thank you VERY MUCH Trevelle! A++
