Delivery & Last-Mile Fleet PM
Delivery Fleet Maintenance in Charleston, SC.

Vehicles We Maintain
PM tuned for high-mileage route work
Box trucks
Engine, brakes, liftgates, and DEF systems serviced so medium-duty box trucks stay route-ready.
Cargo & Sprinter vans
Sprinter, Transit, and cargo vans maintained — oil, brakes, tires, and faults — to keep last-mile units rolling.
Brakes & tires
Stop-and-go routes chew through brakes and tires. We inspect and service both before they fail mid-route.
Batteries & fault scans
Frequent starts drain batteries. We test charging systems and scan for stored codes to catch problems early.
Why On-Site Delivery PM
Protect uptime without pulling vans from route
In delivery, a down van is a missed route and a stack of late packages. Getting that van to a shop and back can cost you a whole day. On-site preventive maintenance removes that trip — we service units at your depot while they are parked, so they never leave the yard just for routine work.
Scheduling PM around your dispatch windows means brakes, tires, batteries, and early faults get caught before they strand a driver. Fewer breakdowns mid-route means fewer emergency swaps, fewer missed deliveries, and a fleet you can dispatch with confidence.
Why operators call us
- Mobile service where the truck is sitting
- Testing before parts replacement
- Clear written findings and next steps
- Commercial diesel and fleet-focused support
- 24/7 Charleston-area availability
What's Included
A PM visit built to keep routes running
1. Engine & fluids
Oil, filters, coolant, and DEF serviced on intervals set for high-mileage route duty.
2. Brakes & tires
Brake wear, tires, and wheel ends checked and serviced — the parts stop-and-go routes hit hardest.
3. Batteries & charging
Batteries, starters, and charging tested so frequent starts do not turn into a no-start at the depot.
4. Liftgates & doors
Liftgates, roll-up doors, and cargo hardware checked so loading and unloading stays quick and safe.
5. Fault-code scan
A scan for stored codes catches aftertreatment and engine faults before they force a van off route.
6. Written record per unit
Each van gets documented findings and recommendations to support compliance and plan the next service.

Delivery fleet maintenance questions
Can you service our delivery vans and box trucks at the depot?
Yes. We come to your depot or lot and perform PM on box trucks, cargo vans, and Sprinters where they park, so units are ready for the next route instead of sitting in a shop.
Can maintenance happen overnight so routes are not affected?
Yes. We schedule PM around your dispatch windows — overnight, early morning, or on off days — so trucks are serviced while parked and back on route on time.
What delivery vehicles do you maintain?
Box trucks, cargo vans, Sprinter and Transit vans, step vans, and light diesel delivery units. We handle most medium-duty and van makes and their diesel and gas drivetrains.
How does PM protect route uptime?
Scheduled service catches worn brakes, weak batteries, and early faults before they strand a van mid-route. That means fewer missed deliveries and fewer emergency swaps. Call or text (843) 310-0995.
