We bring the diesel tech to the truck.

What the mobile diesel tech handles

When a tractor, reefer, box truck, or medium-duty diesel goes down on the highway, yard, or job site, Priority dispatches a mobile diesel mechanic first. The goal is a safe, legal return to service without a tow when that is possible. Dealer-level diagnostics, DPF regenerations and derate clears, air-brake and wheel-end work, jumps, alternators, and charging-system repairs are routine on the shoulder. If the unit cannot be made safe, the same ticket escalates to our heavy wreckers, Landoll, or RGN — or we bring it to the Randallstown diesel shop.

• Roadside first

  Tech rolls before a tow when diagnostics and parts on the truck can clear the derate or restore air and charging.

• Same-company recovery

  Broken frame, seized driveline, fire, or unsafe air — we do not leave you waiting on a brokered second company.

• Fleet & owner-operators

  One number for night calls, weekend breakdowns, and follow-up shop work at Randallstown.

• Not auto repair

  This service is diesel commercial equipment. We do not market passenger-car auto repair.
