Before you call
A few things
worth knowing.
What should I send when requesting service?
Your exact location or map pin, truck make and model, the problem and any fault codes. Photos can help us understand the repair and parts needed.
How soon can you arrive?
Arrival time depends on your location and our current schedule. Call us for availability and an estimated arrival time before dispatch.
Can every repair be done on the roadside?
Some repairs need a shop or a safer location. We’ll discuss the issue and confirm the repair options based on access, tools and available parts.
How much does a service call cost?
The cost depends on your location, the repair and parts required. Call with your truck details so we can discuss call-out and labor charges.
Do you work on my truck model?
We focus on heavy-duty diesel trucks and trailers. Tell us the make, model and repair needed so we can confirm whether we can assist.
