Mobile Diesel Mechanic — FAQ
Do you come to me, or do I bring my truck to you?
We come to you. Our mobile diesel mechanic service is fully equipped to work wherever your truck is parked — roadside, at a truck stop, or in your yard — throughout Middle Tennessee and Southern Kentucky, 24/7.
What diesel problems can you fix on-site?
No-starts, fuel systems, injection pumps, turbochargers, electrical and sensor faults, DEF and aftertreatment, air and brake issues, and charging and starting systems. We handle most repairs short of tires.
Are you available nights, weekends, and holidays?
Yes. Mid-South Road Service runs 24 hours a day, 7 days a week, 365 days a year.
What diesel engines do you work on?
Cummins, Detroit, PACCAR / Paccar MX, Volvo, International, and more — most major heavy-duty and medium-duty diesel engines.
Do you work on fleets?
Yes. Fleet trucks are welcome, and we can keep multiple units moving with on-site repairs and inspections.
Do you do tires?
No — tires are the one thing we don't handle. For everything else on a truck or trailer, we're your one call.
