24/7 Diesel Repair
Dallas-Fort Worth · 24/7 mobile diesel RV repair
Your diesel pusher won’t start at the RV park. Or your Super C went into derate on I-20 with 300 miles left on the trip. Hawkeye Diesel Repair sends a diesel mechanic to your coach 24 hours a day, 365 days a year, anywhere in the Dallas-Fort Worth metroplex. We work on the engine, transmission, brakes, and chassis that get your RV down the road.
Most calls get a technician on-site in 30 to 75 minutes. When a repair needs a lift or a teardown, our shop in Mansfield, TX handles it.
Call (682) 231-8338. A live dispatcher answers, takes your location, and explains our rates before a truck rolls.

Explained before we roll
RV repair covers two different jobs. One is the house: slide-outs, appliances, roof, plumbing, and awnings. The other is the diesel engine and chassis underneath. Hawkeye is a diesel shop. Our technicians repair Class 8 trucks every week, and a diesel pusher shares much of the same hardware: a Cummins engine, an Allison transmission, air brakes, and air ride suspension.
That is the work we do on your RV. If your coach won’t start, won’t make power, is overheating, or is throwing a derate warning, call us.
Class A
Most diesel pushers ride on Freightliner or Spartan chassis with a rear-mounted Cummins engine. Our technicians service the ISB 6.7, ISL 8.9, and ISX15 and X15 platforms, plus the Allison automatic transmissions, air brakes, and airbag suspension on these coaches. We also work on older coaches with Caterpillar engines.
Super C
Super C RVs are built on medium-duty truck chassis, mainly the Freightliner M2 106 and the Ford F-550. That puts them squarely in our lane. We service the Cummins engines on M2-based coaches and the 6.7L Power Stroke on Ford-based models.
Other
If your motorhome runs on diesel, call and tell us the chassis, engine, and model year. Our dispatcher will tell you straight if it is work we handle.
Battery load tests, cables, starters, and alternators. A coach that sat in storage for months often shows up as a no-crank. We test the chassis batteries and charging system before we leave, so you know it will start again tomorrow.
Most diesel pushers and Super Cs built after 2010 run a DEF and SCR system. When a DEF pump, NOx sensor, or DPF pressure sensor fails, the ECM cuts power to protect the engine. We scan the ECM with OEM-level tools, test the sensors, and run a parked or forced DPF regeneration. Learn more about our diesel engine repair work on Cummins platforms.
A diesel pusher’s cooling system works hard on a Texas summer climb. We replace coolant hoses, belts, thermostats, water pumps, and radiators, check the fan clutch, and pressure test the system to find the leak.
Fuel filters, lift pumps, injectors, and priming air out of the lines. Diesel that sits in the tank through a long storage season can cause hard starts and power loss. Our post on clean diesel fuel in DFW explains what to watch for.
Brake chambers, air lines, air dryers, and slack adjusters. If your coach won’t build air pressure, it can’t safely move. We trace the leak and fix it where you’re parked. Airbag suspension service is handled at our Mansfield shop.
Allison fluid and filter service, shift solenoid replacement, and diagnostics for a transmission that is slipping or stuck in limp mode.
Boost leak testing, actuator replacement, and turbo repair when your coach loses power on a grade or blows black smoke.
Oil and filter changes, fuel filter replacement, air filter service, coolant checks, Allison fluid service, and a multi-point inspection before a long trip. Call to schedule a visit at your home, storage lot, or our shop.
A 40-foot diesel pusher is not easy to move when something is wrong. A tow costs time and money, and you may lose your campsite. Our mobile diesel repair trucks come to you: the highway shoulder, a truck stop, an RV park, a storage lot, or your driveway.

The more we know before we roll, the better the odds we fix it on the first visit.
If you’re on a highway shoulder, turn on your hazard flashers and set reflective triangles if you carry them. Keep everyone inside the coach or well away from traffic until help arrives.
For jump starts, fuel delivery, lockouts, and tire changes, see our 24/7 roadside assistance page.
Some repairs need a lift, a press, or a full teardown. Those jobs come to our diesel shop in Mansfield, TX at 6330 Dick Price Rd. It is the same team that diagnosed your coach on-site, so nothing gets lost in the handoff.
What we have at the shop:
Shop work for diesel RVs includes in-frame engine overhauls, head gasket repair, transmission work, DPF cleaning and replacement, radiator replacement, and airbag suspension service.
If your coach can’t be driven, we set up a heavy-haul tow to Mansfield and keep you updated at every step. You only pay for a tow if one is truly needed.
24/7 dispatch
Shop hours run Monday through Friday, 8:00 AM to 5:30 PM, and every other Saturday, 8:00 AM to 12:00 PM. Mobile dispatch runs 24 hours a day, 7 days a week.
You don’t need a local shop or a prior relationship to get help. A breakdown on the way to West Texas, the Hill Country, or the Gulf Coast gets the same response as one in our own backyard. Our mobile units leave from Mansfield, near the center of the metroplex.

Quick answers for diesel pusher and Super C owners.
Yes. Our mobile technicians come to your coach wherever it sits in the DFW metroplex, including RV parks, campgrounds, storage lots, truck stops, and highway shoulders. Give the dispatcher the park name and your site number.
No. Hawkeye works on the diesel engine, transmission, brakes, suspension, and chassis electrical system. For slide-outs, appliances, roofs, plumbing, and awnings, you need an RV house systems technician.
Often, yes. We scan the ECM, test the DEF and NOx sensors, and run a parked or forced regeneration. If the filter is too loaded or a part has to be ordered, we tow the coach to our Mansfield shop.
Yes. We service the 6.7L Power Stroke on Ford F-550 based Super C motorhomes, as well as the Cummins engines on Freightliner M2 based models.
Cost depends on the repair, the parts, and the time of day. A jump start costs less than a brake chamber or water pump replacement. Our dispatcher explains the dispatch fee and hourly rate on the phone, and the technician quotes the repair before starting work.
We set up a heavy-haul tow to our Mansfield shop and keep you updated until your coach is ready. You only pay for a tow if one is truly needed.
