A landscaping company owner walks in on a Tuesday holding the keys to a 2019 F-350 with a check engine light and a shudder under load. He’s got two more trucks parked at his yard and no shop that will take them without a two-week wait. He looks at your open bay and asks the question that could reshape your business: “Can you guys work on this?”
That moment is playing out at independent shops all over the country. The trucks keep coming, and a lot of car-focused owners are quietly wondering whether they should turn part of their operation into one of the truck repair shops their commercial customers are begging for. Before you commit a bay to it, look at the numbers.
The Money Is Real, and So Is the Overhead
Start with the upside. A typical passenger-car repair order at a well-run independent runs $450 to $650. Medium-duty and light commercial truck work routinely lands between $900 and $2,400 per visit, because the parts cost more, the labor times are longer, and the failures are bigger. A brake job on a three-quarter-ton work truck can bill $1,100 where the same job on a sedan bills $500.
Truck repair shops also get repeat volume you don’t have to chase. A contractor with five trucks isn’t shopping around every visit. If you keep his fleet running, he brings all five, plus the crew’s personal vehicles, plus referrals to other contractors who all know each other.
Now the overhead. A two-post lift rated for cars tops out around 9,000 to 10,000 pounds. A loaded F-350 or a box truck can exceed that. A heavier two-post or a four-post lift runs $4,500 to $12,000 installed. Add larger jack stands, a bigger air compressor if you’re running impact tools all day, and diesel diagnostic software that can cost $1,500 to $3,000 a year on top of your existing scan tools. You’re looking at $15,000 to $30,000 to do it right, not counting the bay you take out of car rotation.
Where the Margin Actually Comes From
The mistake owners make is assuming truck work is just car work with a bigger invoice. The margin lives in three specific places, and each one has a number attached.
First, labor efficiency on diesel. If your techs aren’t trained on common Duramax, Power Stroke, or Cummins failure patterns, a job that should take four hours takes seven, and you eat the difference on flat rate or lose it on the clock. Budget for training before you budget for the lift.
Second, parts availability. Truck parts have longer lead times. A turbo or an injector set for a 6.7 Power Stroke might be two to five days out. If that truck is sitting in your only heavy bay, you’re not billing anything on that stall while you wait. Truck repair shops that run tight track parts holds obsessively, because a stalled job on a big bay is far more expensive than a stalled job on a car lift.
Third, scheduling discipline. A three-day truck job blocks a bay that could otherwise turn six oil changes and two brake jobs. If you can’t see that trade-off at a glance, you’ll say yes to work that quietly wrecks your throughput. This is exactly the kind of problem DriveLine’s job board and scheduling are built to make visible.
A Realistic First-Year Model for a 3-Bay Shop
Say you convert one of your three bays to handle light commercial and medium-duty work. Here’s a conservative model.
You take on 12 fleet accounts averaging 4 trucks each, so 48 trucks in rotation. Each truck comes in roughly three times a year at an average repair order of $1,400. That’s 144 visits at $1,400, or about $201,000 in annual revenue from that single bay’s truck work.
Against that, subtract your setup amortization, say $25,000 spread over three years, so about $8,300 in year one. Subtract higher parts costs and the occasional stalled bay from parts delays, call it a 6 percent efficiency drag versus car work. You still clear well past what that bay produced turning quick car jobs.
The catch is the ramp. Fleet relationships take 6 to 12 months to build. Your first quarter might be two or three trucks a week, not fleets rolling in. Plan cash flow for a slow start, and don’t gut your car business to chase trucks before the commercial demand is proven.
Deciding If Your Shop Is a Fit
Not every shop should do this. Ask three questions honestly.
Do you have a tech who wants diesel work, or are you willing to pay to train one? Do you have the bay height and lift capacity, or the space to add it? And can your management system handle longer, parts-dependent jobs without them falling through the cracks?
That last one trips up more shops than the mechanical side. If your scheduling and job tracking still live on a whiteboard or a desktop in the back office, adding multi-day truck jobs will overwhelm it fast. It’s worth reading what happens when your software is trapped on a back-office desktop before you scale up the complexity of your work.
If you’re evaluating tools to handle bigger, longer jobs and fleet communication, our software comparison and the shop management software buying guide walk through what actually matters when your job mix gets more complicated. Fleet managers also live on text, so texting software that sends approvals and status fast is what keeps those accounts loyal.
Frequently Asked Questions
Isn’t truck work just going to slow down my car business?
It can, if you don’t protect your car bays. The shops that make it work carve out one dedicated bay for truck jobs and keep their car rotation running on the others. The risk is real, but it’s a scheduling and visibility problem, not a reason to skip the opportunity. When you can see every bay and every job at a glance, you catch the trade-off before it hurts you.
I don’t have a diesel guy. Is it even worth trying?
A lot of light commercial work is gas-engine trucks and standard drivetrain, brake, and suspension jobs your current techs can already handle. You don’t need a diesel specialist to take a fleet of half-ton work trucks. Save the heavy diesel diagnostics for phase two, once the volume justifies the training and the tooling.
Fleet customers always want a discount. How do I keep any margin?
Fleet accounts trade a slightly lower rate for volume and predictability, and that’s a fair deal when it’s structured right. The margin comes from uptime, not discounts. Track your parts, keep jobs moving, and bill for the diagnostic time you actually spend. A fleet that trusts you to keep trucks running will pay a fair rate all day, because a truck that isn’t earning costs them far more than your invoice.
