Mobile Diesel Repair Hourly Rate: What to Charge
Mobile diesel labor is typically billed at or above local truck shop rates, because you're bringing the shop to a shoulder. On top of the hourly rate you bill a call-out fee, travel beyond a free radius, a separate diagnostic rate, and a published after-hours premium — never a single inflated hourly number.
Four numbers, not one
| Line | What it prices |
|---|---|
| Call-out | Responding at all |
| Travel | Beyond a stated free radius |
| Diagnostic | Skilled time + scan tooling |
| Labor | The actual repair |
Plus a published after-hours premium applied as its own line.
What justifies a higher rate
- Full mobile shop — welder, air, press, tooling
- Manufacturer-level diagnostic software
- 24-hour response capability
- Specialty work (aftertreatment, electrical, hydraulics)
Owner-operators vs fleets
- Owner-operator — card or payment link at the truck, no terms
- Fleet — same-day invoice with unit number, VIN, and mileage, on agreed terms
Extend terms to someone you haven’t set up as an account, and you’re basically financing a stranger — that’s how a lot of mobile techs end up underwater.
Complete beats fast
An invoice missing the unit number, location, or hours just sits in an AP pile until someone bothers to work it out. Get all of it on there before you leave the shoulder.
Frequently asked questions
Should mobile rates be higher than shop rates?
At or above, yes. You're providing uptime at the customer's location with a fully equipped truck, and fleets budget for that premium — what they reject is an unexplained number.
Why bill diagnosis separately?
Because it's skilled work with expensive tooling behind it and it happens whether or not a repair follows. Folded into repair labor, you give it away on every job that doesn't convert.
How much should the after-hours premium be?
A meaningful, published step up for nights, weekends, and holidays. Fleets accept a stated premium; they dispute a labor rate that mysteriously changes at 10pm.
How do I get paid faster by fleets?
Invoice the same day from the truck with a payment link and complete unit-level detail. Late invoices start a payment cycle late, which is most of why haulers wait sixty days.
