Air leak, no-start, DPF derate, DEF fault, blown hose, reefer that stopped cooling, or a trailer that will not roll. Call one number and a stocked service truck heads to your exact location — shoulder, dock, yard, or truck stop — with a diagnosis on scene instead of a tow to somebody else's queue.
The math behind mobile repair is downtime, not labor rate. A stopped Class 8 truck stops everything attached to it — the driver's hours, the trailer, the load, the delivery appointment, and the next dispatch that was already planned around it. For an owner-operator that is straightforward lost revenue on a day that still costs the same in truck payment and insurance. For a fleet it compounds: a truck down at a shipper is a missed dock window, a detention charge, a driver burning clock, and often a second tractor pulled off its own run to recover the freight. Once you price the day rather than the repair, spending more on a mechanic who arrives in ninety minutes than on a tow to a shop that can look at it Thursday stops being a close call.
Towing to a shop does not just add the tow — it adds the queue. A truck arriving on a hook at four in the afternoon is not a truck in a bay; it is a truck in a lot behind everything already scheduled, and it typically loses a full shift before anyone opens the hood. Mobile repair collapses that. The mechanic plugs into the ECM where the truck sits, reads active and inactive fault codes instead of inferring from symptoms, and a genuinely large share of commercial breakdowns turn out to be things a stocked service truck can finish on the shoulder: a chafed air line, a failed sensor putting the engine into derate, a corroded ground strap, a leaking coolant hose, a dead battery bank, a slack adjuster out of spec, a reefer that lost its fuel prime. The truck leaves under its own power, the load stays on schedule, and there is no second call to arrange transport back from the shop.
We are equally direct about what does not get fixed at a rest area. Internal engine work — a dropped valve, spun bearings, a cracked head, injector cup failure into the coolant — is a shop job. So is transmission or clutch removal and replacement, differential and driveline rebuilds, frame and fifth-wheel structural repair, DPF filter baking and ash cleaning, most aftertreatment tear-downs, and anything that requires the vehicle on a lift or in a bay for a controlled evacuation and recharge. In those cases the honest answer at intake is a heavy-duty tow, and our dispatcher will say so rather than sending a mechanic to bill you a diagnostic to reach the same conclusion. What decides it in practice is usually the driver's clock and the load: a fix that gets a rolling truck back on the road before the fourteen-hour window closes is worth reaching for; a repair that will not finish before the driver is out of hours is better handled as a tow to a facility with a bay, a lift, and a parts counter.
Chafed and blown air lines, leaking glad hands and gladhand seals, failed relay and quick-release valves, air dryer cartridges that will not purge, governor faults, and slack adjusters out of stroke. The mechanic soaps the system to find the leak instead of chasing it, replaces the failed component, and rebuilds pressure before you leave. Emergency spring brakes locked up on the shoulder are one of the highest-frequency calls in the category.
Trucks in derate because a regen will not complete, a differential pressure sensor is reading dirty, a DEF quality or level sensor has failed, the DEF pump or header has crystallized, or the NOx sensor has gone out of range. On scene the mechanic pulls fault codes, commands a parked regen when the truck is a candidate, and replaces the failed sensor, injector, or line. Filters that need baking and ash cleaning go to a facility — we will tell you which one you have.
No-crank and no-start diagnosis done properly: battery bank load tested individually, cables and grounds inspected for corrosion, starter draw measured, alternator output verified under load. Also lighting circuits that fail a DOT stop, corroded seven-way connectors, chafed harnesses, blown fuses that keep blowing, and jump-start plus battery replacement in the truck-stop parking lot at three in the morning.
Split coolant hoses, failed clamps, leaking water pumps, thermostats stuck open or closed, radiator and charge-air-cooler leaks found and confirmed, plus fan clutch faults that show up as a high-temp derate on a grade. On the fuel side: gelled fuel in a cold snap, plugged filters, air in the system after a filter change, lift pump failures, and priming a truck that ran itself dry.
Trailer landing gear that will not crank, bent or seized legs, ABS lamp faults, lighting and seven-way wiring, air lines and spring brake chambers, door and hinge hardware, and suspension airbags. On refrigerated units: no-cool and no-start diagnosis, belts, alarm codes, fuel and battery faults, and defrost issues. APU no-start and charging faults get the same treatment so the driver is not sleeping without heat or air.
Scan-tool diagnostics for engine, transmission, ABS and body controllers so the repair starts from data. We also fix the items that put a unit out of service at a scale: lighting, air leaks over spec, brake stroke, mud flaps, tire condition, and load securement hardware — and can run a mobile annual DOT inspection at your yard so it is not discovered on the road.
Every hour a commercial unit sits is billing against you in three directions at once — the load that is late, the driver whose clock is running whether the truck moves or not, and the next dispatch that has to be rearranged around it. A mechanic at the truck ends that clock where the truck already is, instead of adding a tow, an intake, and a night in somebody's lot before anyone diagnoses it.
Network service trucks roll with heavy-duty scan tools and OEM-level software, air line and fitting stock, glad hands, brake chambers and slack adjusters, filters, belts, hoses and clamps, DEF and coolant, group 31 batteries and cable ends, jump and welding capability on many units, air compressors, torque equipment, and lighting for night work. Heavy-duty wreckers are dispatched on the same ticket when the repair belongs in a bay.
Mobile repair is not one job. A reefer that stopped cooling and a motorcoach with a charging fault need different techs, different parts, and different trucks. Find your equipment so you know who is coming before you call.
The heart of the network's commercial volume. Day cabs and sleepers across every major engine family, where most calls are air system, aftertreatment, electrical, or cooling — and where a completed roadside fix saves the load, not just the repair bill.
Trailer faults strand freight just as hard as engine faults, and they are usually faster to fix. Landing gear, ABS and lighting, air and brake hardware, suspension airbags, plus refrigerated units that quit cooling with temperature-sensitive product already loaded.
A motorhome is a house and a truck failing at the same time, usually far from home with a family inside. Chassis-side work runs the same as any diesel: charging, air, cooling, fuel. House-side work is generators, shore power, slide-outs, and leveling.
Passenger units and vocational equipment carry a schedule and, often, people waiting on the shoulder. Priority is a safe, fast return to service — air, charging, door and wheelchair-lift systems, HVAC, and the hydraulics that vocational bodies depend on.
Patterns pulled from live dispatch traffic across the network, not a generic service checklist.
The truck loses power, the dash lights up, and speed falls to a crawl in the right lane. Most of the time this is aftertreatment: a regen that has not completed, a differential pressure sensor reading a plugged filter, a DEF quality or level fault, or a NOx sensor out of range. The mechanic reads the actual fault codes rather than guessing from symptoms, and where the truck qualifies, commands a parked regen or replaces the failed sensor on the spot. If the filter itself is loaded with ash, that is a facility job and we will tell you straight instead of billing an hour to say so.
Pressure will not build, the buzzer will not stop, or the spring brakes drop and the truck is anchored where it sits. Usually a chafed line rubbing a frame rail, a failed glad hand seal, a leaking relay or quick-release valve, or an air dryer that has stopped purging. Because it is a brake system the fix is not a wrap of tape — the mechanic finds the leak, replaces the failed component with the correct line and fitting, and verifies the system builds and holds to spec before the truck moves.
The most common overnight commercial call there is, and it spikes on the first hard freeze. It is rarely as simple as one dead battery: batteries in a four-battery bank fail individually, corroded ground straps mimic a bad starter, and a weak alternator will kill a fresh bank in two days. The mechanic load tests each battery, measures starter draw, and verifies charging output under load, so you find out on scene whether you are good to Chicago or need a bank replaced before you roll.
The clock on this call is the load, not the truck. Refrigerated units quit for a short list of reasons — fuel starvation or a plugged filter, a dead unit battery, a shredded belt, a failed sensor, a defrost cycle stuck on, or an alarm code locking the unit out. A tech gets the unit running and pulls the code so you know if it will hold to the receiver. If the box cannot be saved, dispatch can help you move on a transload before the claim gets worse.
The crank handle will not turn, the legs will not lower, or one leg is bent from a dock hit and the trailer cannot be dropped or picked. Not glamorous, and it stops the operation cold — a tractor stuck under a trailer is two assets down instead of one. Mobile repair frees or replaces the gear where the trailer is parked, which is the only option that makes sense, because a trailer with bad landing gear is exactly the thing you cannot move to a shop.
A Class A that overheats on a mountain pass or a coach whose chassis batteries will not hold overnight puts a family in a parking lot with nowhere to go. Chassis-side, the diagnosis is ordinary heavy-truck work: coolant hoses, fan clutch, belts, charging system. House-side, it is generators, shore power, inverters, and slide-outs that will not retract. Either way it is service where the RV is parked, so nobody is booking a motel while a coach sits in a shop lot.
Rolling 30-day average dispatch-to-arrival by service type across the national rescuer network. Urban metros run faster; rural corridors run longer.
Dispatch does the finding. You never call a second company, chase a callback, or negotiate with a stranger on the shoulder.
Air leak, no-start, DPF derate, DEF fault, blown hose, reefer that stopped cooling, or a trailer that will not roll. Call one number and a stocked service truck heads to your exact location — shoulder, dock, yard, or truck stop — with a diagnosis on scene instead of a tow to somebody else's queue.
Nobody can quote a national flat rate on commercial repair honestly, because the same fault code costs different money depending on where the truck sits, what time it is, and whether the part is on the service truck or three hours away. Here is what actually sets the number so you can judge the quote before you approve it.
These are two different clocks. Pulling codes and confirming a failure on a truck with an obvious symptom can be quick; chasing an intermittent electrical fault or a slow air leak through a chassis harness is not. Straightforward jobs where the failure announces itself bill less time than the ones where finding it is most of the work, and dispatch will tell you which one your symptoms sound like.
A repair using stock already on the service truck — air line, filter, belt, hose, batteries, common sensors — finishes in one trip. A part that has to be sourced from a dealer counter, and especially one that is not local or is behind an OEM order, adds runner time and can turn a same-visit fix into a return trip. Older and less common engine families and vocational bodies are where this bites hardest.
Overnight and holiday work carries a higher labor rate everywhere in this industry, because fewer mechanics are on call and demand spikes at the same moment during a cold snap or a storm. If the truck is legitimately parked and the driver is on a break anyway, waiting for a daytime slot is sometimes the cheaper decision — and that is a call we will help you make rather than talk you out of.
Someone has to drive a stocked service truck to you and back. A breakdown at a metro truck stop with several qualified providers nearby prices differently than the same fault at a rural exit ninety miles from the closest heavy-duty mechanic. Location is often the single largest variable on a commercial ticket, and it is the one nobody can quote before they know where you are.
If the on-scene diagnosis lands on internal engine damage, a transmission that has to come out, or frame and structural work, the right answer stops being repair and becomes heavy-duty transport. That changes the cost structure entirely — hookup plus per-mile to the facility you choose. Dispatch confirms the tow number before hookup, and choosing a capable nearby shop over a distant dealer is usually the biggest saving on the ticket.
Fleets running volume through the network get negotiated rates, purchase-order and reference-number handling, consolidated invoicing, and repair documentation formatted for maintenance records rather than a paper receipt handed to a driver. A single owner-operator calling once pays the network rate for that job. Both get the same mechanic; the difference is commercial terms and paperwork.
You get the price before the truck rolls. Dispatch quotes the job up front against the network rate for your location and equipment, and we confirm it with you before anyone is dispatched. No arrival-time surprises, no renegotiating on the shoulder.
Three steps from breakdown to back on the road. Same flow whether you call from a fleet desk or the shoulder of an interstate.

The deep reference for commercial truck service: systems we repair on site, what belongs in a bay, and how fleet accounts and documentation work.
Network average for commercial mobile repair runs a little over an hour from dispatch to on-scene. Along dense freight corridors and near major truck stops it is often inside 45 minutes. On rural two-lanes, in mountain terrain, overnight, or during a regional storm it can stretch past two hours, because the nearest qualified heavy-duty mechanic is genuinely far away. Dispatch gives you the real number at booking and calls you if it moves.
More than most drivers expect. Air lines, glad hands, valves and air dryers; batteries, starters, alternators, grounds and harness faults; coolant hoses, thermostats, water pumps and fan clutches; fuel filters, priming and gelled fuel; DEF and DPF sensors, injectors and lines, plus commanded regens; trailer landing gear, lighting, ABS and airbags; reefer no-cool and no-start; APU faults; and DOT out-of-service items. Roughly three out of four commercial calls in the network finish on scene.
Internal engine work — dropped valves, spun bearings, cracked heads, injector cup failures into the coolant — is a bay job. So are transmission and clutch removal and replacement, differential and driveline rebuilds, frame, suspension and fifth-wheel structural repair, DPF filter baking and ash cleaning, and most aftertreatment tear-downs. If that is where the diagnosis points, we say so and convert the ticket to heavy-duty transport to a facility you choose.
Yes, and trailer calls are a large share of the volume. Landing gear, ABS faults, lighting and seven-way wiring, air lines and brake chambers, suspension airbags, and door hardware are all standard mobile work. On refrigerated units we diagnose no-cool and no-start conditions, alarm codes, belts, fuel and battery faults, and defrost problems, with the goal of holding temperature to the receiver.
Often, yes. If the truck is a candidate, the mechanic commands a parked regeneration on scene, and many derates trace to a failed sensor, a DEF quality or level fault, a crystallized header or line, or a wiring problem that gets replaced right there. What cannot happen roadside is baking and ash-cleaning a loaded filter — that requires a facility with the right equipment, and the mechanic will tell you which situation you are in before you spend money.
Yes. Chassis-side work on a Class A or Super C is ordinary heavy-truck repair — charging systems, air, cooling, belts and hoses, fuel. House-side we handle generators, shore power and inverter faults, slide-outs that will not retract, and leveling system problems. Service happens where the coach is parked, including campgrounds, rest areas, and storage lots, so a trip does not end in a shop lot two states from home.
Fleets set up an account with negotiated rates, and dispatch captures your unit number, PO or reference number, and driver contact on every call. You get consolidated invoicing instead of drivers handing in receipts, and repair documentation written for maintenance files — fault codes, parts used, labor, and unit identification. Setting up an account costs nothing; call (800) 673-1060 and ask for fleet dispatch.
Every provider is verified before taking a dispatch and re-verified on an ongoing basis: current commercial general liability and garage-keepers coverage, valid operating authority, and equipment matched to the work they accept. Heavy-duty calls only route to providers who carry heavy-duty scan tools and stock. Performance is tracked on arrival time, first-visit completion, and comeback rate, and providers who fall below standard stop getting dispatched.
Usually, once you price the whole event instead of the line item. A tow costs the hookup and mileage, then adds the shop queue — a truck arriving at four in the afternoon typically loses a shift before anyone opens the hood — plus a driver who needs transport and lodging, and freight that is now late. When the fault is genuinely roadside-repairable, mobile is both faster and cheaper. When it is not, the tow is the right answer and we will say so.
Yes, across 48 states, including the corridors where commercial breakdowns actually happen and where local heavy-duty coverage is thin. Dispatch is staffed around the clock, including nights, weekends, and holidays. In remote areas we quote the honest arrival window rather than a metro ETA you will never see, and we tell you if the smarter play is a tow to the nearest facility instead of waiting on a mechanic.
Network rescuers accept all major credit cards, fleet cards, and consumer payment apps. Confirmed at dispatch.
