On-Site Repairs

We Also Offer Truck Pickup Service — We Come to You & Bring It Back

Not every breakdown can be fixed roadside. When a repair requires shop equipment, our team offers vehicle pickup service — we dispatch a truck to your location, transport your vehicle to our facility, complete the repair, and deliver it back to you.

This is especially useful for fleets that cannot afford downtime waiting for a tow, owner-operators managing tight schedules, and situations where the breakdown location is not accessible for extended repair work. We handle the logistics so you can focus on your business.

  • We come to your breakdown location and assess on-site first — most repairs completed there and then.
  • If a shop repair is needed, we coordinate pickup and transport so no third-party tow company is required.
  • Available for semi-trucks, box trucks, trailers, heavy duty vehicles, and commercial fleets.
  • Serving Dallas–Fort Worth, Las Vegas, and Oakland — call to confirm availability in your area.
🚛

On-Site Assessment First

We always come to you first and try to fix roadside. Pickup is arranged only when a shop repair is the best solution for your truck.

icon

No Third-Party Tow

We handle the full process in-house — no need to coordinate with a separate tow company or wait for multiple service calls.

icon

Upfront Pricing

You get a full estimate covering pickup, repair, and return delivery before we begin. No hidden costs, no surprise charges.

icon

ECM Diagnostics & Scans

Our shop prioritizes pickup vehicles so your truck is repaired and returned to service as quickly as possible.
