Naperville, IL
All day, your trucks work Naperville’s office parks, retail centers and neighborhoods. At night they sit. That’s when we show up. Our mobile diesel mechanics service your units in the lot where they park, so every truck starts the morning ready to run.
What we offer
Naperville fleets run a mix of medium-duty delivery trucks and Class 6-8 units, often parked at business parks rather than dedicated truck yards. Our commercial fleet services are built to fit that setup.
Medium-duty and Class 6-8 PMs in your lot, overnight or on weekends
Air brake repair and adjustments
Mobile diesel repair for no-starts, electrical faults and leaks, day or night
DOT inspections and pre-DOT audits
Mobile truck repair on I-88, I-355 and Route 59 when a unit goes down mid-route
Battery, alternator and starter testing before winter hits
WHY CHOOSE US
You send us your fleet list and yard hours, and we set the PM schedule. Our technicians service your trucks where they’re parked, and every inspection goes into your Fullbay fleet portal with photos and video, so you can approve repairs with one click. Every repair is backed by our 90-day / 10,000-mile labor warranty and $2,000,000 in liability coverage, and one fleet maintenance contract covers your trucks and trailers. Start with a complimentary 50-point yard safety audit.

FAQs
We run a smaller fleet. Do you work with operations our size?
Yes. We build proposals for fleets starting at 5 units, and medium-duty trucks are covered on the same program as Class 6-8 units.
Can you service our trucks at a business park lot instead of a truck yard?
Yes. As long as our technicians are authorized to work on the property under your Master Service Agreement, we can service your trucks wherever they park.
Do I need a contract to call you for a breakdown on I-88?
No. Any commercial truck can call dispatch for emergency service. Fleets on a maintenance program get priority in the dispatch queue.
How do you keep track of when each truck is due?
Each unit goes on an automated PM schedule by mileage or engine hours, so you’ll know which trucks are due for PM-A, PM-B or PM-C before the date arrives.
Do you offer Net-30 billing?
Yes. Net-30 terms are available to approved accounts once a business credit application is completed.
