Learn moreWhy operators keep calling us back
Nothing here is a slogan. Each of these is a decision about how the work gets done, and you can hold us to all six.
The fault gets proven before parts are ordered
We connect on manufacturer software, capture live data and test the component the code points at. Repeat repairs are a diagnosis problem, not a parts problem.
Service trucks that arrive with the parts
Common tire sizes, batteries, air components, belts, hoses and filters ride on the unit. That inventory is why most roadside calls end with the truck driving away.
Hours we actually keep
Open six days a week, 6:00am to 4:00pm, and closed on Sunday. We would rather publish the hours we work than a number that sounds better and leaves you calling a machine.
Measurements written down, not check marks
Brake stroke by wheel end, tread depth by position, fluid conditions. Numbers you can trend, and a maintenance file that survives an audit.
DOT work done by qualified inspectors
Annual inspections on tractors and trailers with the documentation and the decal, plus honest reporting of what we found and what you declined.
A straight answer when the repair is not worth it
If a job belongs at a dealer under warranty, or the truck is not worth the money at that mileage, we will say so rather than quoting it and staying quiet.

How a call actually goes
No mystery to it. This is the sequence from the moment you dial to the moment the paperwork lands.
- 1
Call or send the request
Give us the location, the unit, what it is doing and whether you are loaded. Those four things decide which truck we send and what goes on it.
- 2
We confirm what it needs and what it costs
You get the call out fee and the labour rate before anybody rolls, and a straight answer about whether the job can be done where the truck sits or needs a bay.
- 3
Repair on site, or a tow if it needs one
Most calls are finished where the truck sits. If it cannot be done safely there, we tell you straight away rather than billing hours on the shoulder.
- 4
Invoice, records and follow up
An itemised invoice with parts, labour and the measurements taken, filed against the unit, plus follow up on anything that still needs shop attention.
What customers say
Owner operators, drayage fleets and local operators from across the Baltimore metro area.
We run eleven tractors out of the port and used to lose a day every time one needed a brake job. They work through our yard on a schedule now and hand back stroke measurements on every wheel end. Our roadside call outs are down by more than half since we started.

When Frame Welding Is Allowed on a Truck, and When It Absolutely Is Not
Frame rails are heat treated steel with published repair rules. A weld in the wrong place leaves the rail weaker than the crack it replaced.

Questions we get asked most
Class 6 through Class 8 trucks, tractor units, dry vans, reefers, flatbeds, tankers, chassis and vocational vehicles including dump trucks, mixers and roll offs. We also handle medium duty straight trucks and box vans for local delivery fleets.
Both. We run mobile service units across the Baltimore metro area six days a week, and we have shop bays for work that needs a lift, an overhead crane or a controlled environment. Roughly two thirds of what we do is completed without the truck coming in.
Yes. Dispatch is answered Monday to Saturday, 6:00am to 4:00pm. Nights and weekends account for a large share of our roadside work.
We work from Ponca Street in Baltimore and cover roughly a 30 mile radius from there, so the city, the port areas and the inner Beltway ring are the shortest runs and places like Columbia, Owings Mills and Aberdeen are the longest. We will tell you honestly where a unit is and what the run looks like at that time of day rather than quoting you a number we cannot control.
Yes, in most cases. Our mobile units carry the software to command a stationary regen. It needs a location with clearance around the exhaust because temperatures get very high, so we will not do it in a tight spot.
A service call fee covers getting a truck and technician to you, then labour and parts on top. Dispatch quotes the call out fee and the labour rate before we roll, so nothing on the invoice is a surprise.
