## How work is delivered

### Emergency dispatch

Call and a technician is routed to the truck where it sits — roadside, dock or shoulder. Available around the clock across Metro ATL.

Best for: No-start, breakdown, derate on the road, a load that has to move tonight.

### Scheduled on-site work

We book a window and come to your yard or jobsite. Diagnosis, repair and programming happen where the unit is parked, with no bay queue.

Best for: Known faults, follow-up repairs, jobsite equipment, work that can wait for a slot.

### Fleet maintenance program

A recurring schedule across the units you nominate, with written inspection reports so repairs get planned around dispatch instead of interrupting it.

Best for: Operators running multiple units who want fewer surprises and a documented history.

## Process

01. **Tell us what the truck is doing.** Call or send a request with the unit, the engine family and the symptom. Fault codes and when it started help, but they are not required.
02. **We scope it and quote it.** You get a clear description of the work and a price before a technician is dispatched. No open-ended labor.
03. **Diagnosis at the vehicle.** Live data, circuit testing and load testing at the truck. We find the cause before anything is replaced, and we call you before the scope changes.
04. **Repair, verify, document.** The repair is completed and verified under operating conditions, and you get a written record of what was found and what was done.
