Mobile Truck Repair Specialists in Bakersfield, CA

Your Trusted Mobile Diesel Repair Expert in Bakersfield, CA

Built on Experience, Fueled by Passion

At Plus Ultra Truck Doctor, we’re more than just a repair service—we're the result of a lifetime spent under the hood. Owner and lead technician Derick Delacruz grew up in the diesel world. From turning wrenches beside his dad as a kid to operating a family-owned shop, Derick’s journey is built on grit, experience, and a genuine love for solving mechanical problems.

Over the years, Derick worked at various shops to expand his knowledge. But after the tragic loss of his brother, Derick took one of his brother’s trucks and transformed it into the foundation of his own dream—Plus Ultra Truck Doctor. Since opening in August 2024, he’s been committed to providing honest, transparent mobile diesel repair for truckers, RV owners, and fleet managers across the Bakersfield area.

Our Specialty Services

As a mobile-only shop, we bring full-service heavy-duty repairs directly to you—wherever you’re parked within an 80-mile radius. We’re equipped to handle a wide range of issues on:

• Heavy-duty trucks
• Trailers
• Buses
• RVs

Our specialties include pinpointing and fixing coolant system leaks, resolving electrical issues, and tracking down air leaks—some of the most frustrating and downtime-causing problems in the diesel world. While we try to avoid Volvo truck repairs due to known parts and diagnostic complications, we’re more than ready to tackle any other brand on the road.

No job is too big or too small, and you can always count on Derick to explain exactly what’s going on with your rig. That transparency is what keeps our customers coming back—and their trucks rolling.
