Frank is a very kind and helpful man. I saw his repair truck on Pilot in Tucson, AZ and asked him for a deep socket to replace my oil pressure sensor which I just bought at Freightliner dealership. He not only gave it to me but also helped me to replace my old sensor. Moreover he did it for free. Now I keep his contact for any emergency in Tucson area. Also I highly recommend this guy if you're broken down in the area. Thank you.

Frank at Roadrunner is a very knowledgeable diesel mechanic. He quickly diagnosed a steering problem on my RV and did a permanent fix. He was reasonable and got me back on the road expeditiously so I could have the peace of mind to enjoy the rest of my cross country trip.

Truck went down 20 miles outside Tucson with bad air leak, ended up being braided airline coming off the compressor. 2 guys showed up without any idea what was wrong and had the parts on the truck that they needed! Had us back on the road in less than 2 hours from when we first called them and at a very reasonable price! 10/10 would breakdown here again, lol!!

I had an amazing experience with Road Runner Mobile Diesel Mechanic. Within minutes of calling, Frank arrived with a great attitude and was ready to help with my diesel truck breakdown. As soon as he got there, he asked all the right questions to understand the issue, quickly diagnosed the problem himself, and immediately got to work. He went to the diesel parts store to grab the exact part my truck needed, came back, and had the repair finished within 30 minutes. Fast, honest, and knowledgeable. I highly recommend this mobile mechanic to anyone dealing with a truck breakdown. Frank is awesome.

5+ stars for outstanding service!!! We are so very appreciative for Frank and his roadside truck repair on Thanksgiving Friday. My husband’s semi had a failure in the coolant system that stranded him on the side of I-10 on Thanksgiving evening. Pictures of the parts were sent to Frank, and he was able to determine what was needed. Due to the holiday, parts were not available until Friday morning when the dealer’s part department opened. This dealer was 30 miles from the truck. Frank arrived at the truck mid-morning, and within 2 1/2 hours, the truck was repaired and back on the road! We will certainly call Frank for any future service needs when in the Benson, AZ area! Always happy to frequent a service shop that offers this kind of service!!!

Roadrunner provided excellent service. One of our trucks needed a new brake chamber, and they showed up quickly and got my driver back on the road at a very fair price. As a fleet manager based in Canada, I appreciate their professionalism and efficiency. We’ll definitely be using them again in the future. Thanks to the whole team for the help!
