Mobile Truck Repair and Full Service Shop

Let us help you manage your fleet
without the cost of a Fleet Manager.


Cornerstone Fleet Services Inc provides convenient, cost-effective and comprehensive services for fleet managers and companies. Preventative maintenance and truck repair services can usually be scheduled during the less demanding peak hours, allowing our customers to keep their trucks on the road. No longer is there a need to take a truck and driver off the road to sit and wait for service at a fixed-site location.

"We Come To You" - On a regular schedule or by appointment. Servicing trucks on-site saves costly truck and driver down time. 


Our preventative maintenance inspection offers a systematic and thorough approach to truck maintenance and repair. This program includes inspection of brakes, suspension, electrical system, drive train, exhaust, belts, hoses, pulleys, pumps, cooling system and fluids. This inspection also provides the fleet manager with PM frequency recommendations and report of services performed.


We use specialized computer software that includes, calendar management tracking PM and DOT schedules. We are able to furnish many reports that save fleet managers time. This also allows fleet managers to compile fleet costs with less time. Examples: Truck labor and parts operations, sales reports, truck expenses, recommended repairs.


Think about it, what can be more convenient than having Cornerstone Fleet Services Inc bring the service to you...when you need it? You don't bring your fleet trucks to us for service. We come to you when you need us- routinely or in emergencies.
We service your truck, trailers, or cars at your location and at your convenience. We enable you to utilize your fleet and your personnel to the fullest, without the inconvenience and expense of using one and sometimes two employees to deliver and pick up from the shop.
Your personnel can do what they're paid for-productive work. Your trucks can do what they're purchased for -stay on schedule, without downtime for service when they should be on the road.
Our charges are more than competitive, and our mechanics are qualified to service all of your trucks and your equipment from oil changes to major engine work and transmissions. And 85% of all mechanical work can be done right from our fully equipped trucks at your site. IT'S JUST THAT EASY.


Cornerstone Fleet Services Inc provides emergency road service. In most cases we will have your truck repaired and back in operation with minimal delay, eliminating towing charges, costly down-time expense and schedule disruptions.

" I would like to thank the team at Cornerstone for there great customer service. I am the delivery manager for the Lowe's on Memorial in OKC. I was on inventory when one of my vehicles broke down about 60 miles out of town. Being unable to manage the situation I called your office. The clerk I have always worked with was able to send out service to help my stranded drivers. When we found out it could not be fixed on site she set up the tow for me. She also took the number of my driver and contacted them every step of the way, due to me being unavailable. She then arranged for the transport of my drivers back to the store through the towing company and the tech that came out and looked at the vehicle. It is nice to know that there is someone out there that can handle a tough situation without being asked. Her initiative allowed me to keep on task through out the day while getting my truck and two of my drivers off the side of the road. It is very appreciated!!!!"
