"My semi truck broke down yesterday in the afternoon in Salisbury, NC and i was lucky enough to find these guys to help me fix it. I had issues with electrical cable, and other harness issues. They took me in immediately, fixed it and i was on the road in less than an hour! They were professional and knew what they were doing. Next time I'm around Salisbury area and have issues with my truck i definitely know where to go! Thank you guys...and thank you Spencer!"


"Being the Director of Maintenance with Hilco Transport I can tell you that these guys do a very professional job from start to finish. We had a wrecked cargo tank that needed a good bit of work. Brian Brewer in the shop walked us through the repairs needed going over the tank, providing an estimate for the repairs and kept us informed througout the repair process. Once the tank was complete our in-house tank techs reviwed and were happily impressed. That being said, we have taken them additional work including a cargo tank refurb job. Check these guys out! You will not be let down!"


"Had a problem with the pump on one of trucks being locked up do to driver leaving product in it. Called Brain and he got me in that day and out the next!!! Thanks for getting me in and out as to not miss out on any loads."
