Our PM programs include:

  • Multi-point inspections
  • Engine oil, filters & fluid service
  • Brake, suspension & steering checks
  • DOT compliance checks
  • DPF/after treatment health checks
  • Battery & electrical system testing
  • Tire & tread inspections
  • Scheduled PM service across our Birmingham and Montgomery hubs — including Huntsville, Cullman, Jasper, Monroeville, and reaching toward Mobile and the Gulf Coast
  • Flexible PM days for multi-unit fleets

Alabama Fleet Maintenance FAQs: What Local Fleets Need to Know

What types of fleet vehicles do you service across Alabama?

We work on Class 3–8 commercial vehicles including delivery vans, service trucks, box trucks, medium-duty units, and semis. We also service dry van, refrigerated (reefer) trailers, flatbeds, and utility trailers throughout Alabama, including the Birmingham metro (Huntsville, Cullman, Jasper) and the Montgomery metro (Monroeville), with coverage extending toward Mobile and the Gulf Coast.

Do you provide mobile repairs at our yard, job site, or roadside in Alabama?

Yes. We bring full onsite and mobile repair service just about anywhere in the Alabama metros — whether your truck is in a distribution yard, on a job site, or down on the shoulder. Most issues can be diagnosed and repaired without towing.

What areas do you service in across Alabama?

We cover two hub regions across Alabama: the Birmingham metro — including Huntsville, Cullman, and Jasper — and the Montgomery metro, including Monroeville. We also support fleets operating along I-65, I-59, I-20, and I-85, connecting our teams from North Alabama down through Central Alabama, with reach extending toward Mobile and the Gulf Coast through our Gulf Coast team.

What repairs can you handle onsite in Alabama?

Most day-to-day fleet repairs can be handled onsite, including:

  • Diagnostics & check-engine troubleshooting
  • DPF/DEF/emissions system work and forced regens
  • Electrical, batteries, starters, alternators
  • Brake, wheel-end, and air system repairs
  • PM services & fluid/filter changes
  • Trailer brakes, lighting, wiring, suspensions

If it’s safe to repair onsite, we’ll handle it right where the truck sits.

How fast can you respond to breakdowns in Alabama?

Most Alabama fleets are seen same day, and emergency calls are prioritized based on technician availability. We communicate clearly with accurate ETA updates so you know when help is on the way.

Do you offer scheduled PMs for Alabama fleets?

Yes. We build preventive maintenance programs around your routes, mileage, and OEM intervals. We can service multiple units in one visit and help you stay ahead of breakdowns.

Can you service several trucks during one visit?

Definitely. Many Alabama fleets schedule batch PMs or hand us a repair list when we’re onsite. This keeps downtime low and prevents trucks from coming off the route during business hours.

Do you offer after-hours or weekend service in Alabama?

Yes — after-hours and weekend appointments are available for fleets that prefer off-shift maintenance to keep trucks rolling during the day.

What diagnostic tools do you use?

We run modern diagnostic platforms like AUTEL, JPRO and OEM-level software so we can accurately troubleshoot check-engine lights, emissions issues, electrical faults, and regen problems onsite.

Can you perform DOT inspections onsite in Alabama?

Yes. We offer full annual DOT inspections at your yard or facility anywhere across our Alabama service areas — the Birmingham metro, the Montgomery metro, and other markets across the state.

What industries do you support around Alabama?

Construction, roofing, last-mile delivery, HVAC/plumbing, landscaping, manufacturing logistics, municipal fleets, and service contractors. If your business depends on reliable trucks, we support it.

What payment options do you offer? Can we set up fleet billing?

We offer standard payment options plus fleet billing for qualified accounts. Weekly or per-visit invoicing is available depending on what fits your operation.

How fast can you get parts in Alabama?

We stock common parts on our service trucks and source others same-day or next-day from local Alabama suppliers across our service regions. Our goal is to avoid long waits and get trucks back in service fast.

What makes your mobile service different from other Alabama providers?

We show up when we say we will, diagnose issues accurately, and repair trucks right the first time. Alabama fleets use us because we operate like a partner — focused on uptime, communication, and preventing repeat problems.

Ready to Take the Shop Out of the Shop Visit?

We’re more than a mobile mechanic — we’re Alabama's fleet partner focused on uptime, compliance, and cost control. Our mobile service eliminates unnecessary downtime. Our onsite programs keep operations efficient and on schedule.
