What affects the price?
California, New York, and Texas major metros tend toward higher hourly rates. Rural Midwest and Southeast markets often run $20–$40/hr less.
A general mobile mechanic is less expensive than a certified aftertreatment specialist or refrigeration tech. Match the tech to the job.
Mobile techs typically mark up parts 15–40% over their cost. Ask for an itemized quote so you know what parts cost vs. labor.
Sending your SPN/FMI codes through RoadService.app means the tech knows what they're walking into — fewer diagnostic billable hours, faster resolution.
