We repair them where the freight is moving.
A parked truck earns nothing. Independent shops, TA Truck Service, and dealer networks all fix trucks — but they tow to a single bay and charge you for the downtime. MTG Truck Shops runs 24/7 mobile diesel mechanics along the interstates where your trucks actually break down, backed by four fixed shops and a 90-day national warranty.
- Tow the truck to a shop — hours of downtime and a tow bill
- One location, one trade — drive between shops for tires, brakes, engine
- Business hours only — breakdowns don't wait for 8 a.m.
- Single-state coverage — hand off to strangers at the state line
- Mobile techs come to the truck — roadside, yard, or jobsite, 24/7
- Full scope under one dispatch: diesel, trailer, tires, PM, diagnostics, parts
- 4 fixed shops anchor the network — Brush CO, Green River WY, Harlingen TX, McKinney TX
- I-70, I-76, I-80, I-25, I-2, I-69, US 75 coverage — the freight corridors, not just one ZIP code
Don't tow it. Fix it where it sits.

Thank you Ashton and Tucker for being quick and efficient as well as diagnosing my water pump issues and repaying it as fast as you did
Had a great experience Tucker came really quick an was polite an professional he was extremely helpful in getting my truck loaded on an trailer he also needs a raise 👍
I was stranded on the road because one of my turn signals wasn’t working, and Brandon came to help me out. He was professional, helpful, and made sure I got the assistance I needed. I really appreciate his kindness and quick response. Excellent service! Thank you, Brandon, for helping me when I needed it most. Highly recommended!
Had an excellent experience here,my truck was leaking coolant, and I took it here. They informed me that my radiator needed replaced. Brandon was very informative about timeliness and what needed to be done. They ordered a new radiator and it was damaged in transit, not the shops fault at all They ordered another one and gave me a timeliness of delivery and repair time. They were finished ahead of schedule. Besides Brandon's knowledge and thouralness on completing the job there was another out standing employee, a young tall guy that I cannot remember his name. This gentleman saw the frustration that I was having trying to find a ride in this area as uber is not really responsive and neither is the taxi service, so he was off duty and offered to take me to the airport so I could catch a flight and complete some other things that my company needed attention to. That young man was also on point sorry I cannot remember his name. Just saying you guys need more employees like Brandon and the other gentleman because they are true assets to your company. THANK YOU AGAIN FOR THE REPAIRS AND THE EXTRA HELP!
Tucker was a great technician. He came shortly after I made a service call to get my trailer tail lights fixed. Friendly and helpful guy. 10/10 customer service.
I had an excellent experience thanks to Roy. He was incredibly helpful and professional. Highly recommend!
