From the business
In the shop's own words: “We come to the truck, at any hour”
We are a mobile diesel truck repair service based on Whittram Ave in Fontana. Instead of making you find a way into a shop, we bring the tools and the parts to wherever your truck is sitting: the yard, the shoulder, a customer's dock.
Our phone is answered 24 hours a day, every day of the week. Drivers have called us at midnight and had a mechanic on site with the right parts already loaded. When the fix is straightforward, we get it done and get you rolling instead of putting you in a queue.
Owner-operators and small fleets make up most of our work, and they come back. Sixty-seven customers have rated us on Google and every one of them left five stars.
- Fully mobile: we come to you
- Open 24 hours, including nights and weekends
- 5-star rated by 67 Google reviewers
- Straight answers and fair pricing
