"Bob, Scott, and Blake are phenomenal! My truck had all the after treatment lights come on and derated. I tried several places to get worked on and no one could or would work on it. I called MTSR and informed them of the situation; Bob made a road call and after being unable to fully diagnose the problem, towed truck to the shop. Bob and Scott immediately set into finding the issue and after several hours the cause was found. The after treatment fuse box cap had displaced and fuse box filled with water. They remedied the situation, and then I had a PM done and steer shocks replaced. In 24-26 hrs from my call to MTSR, my truck is back on the road. The guys at MTSR are friendly, prices are fair and good, and the work exceptional. I will be returning for any other work needed."
