About JS Mobile Repair

Mobile Diesel Repair Done Right

We built this business on one simple idea — you shouldn't have to tow a truck that can be fixed on the spot.

Our Story

JS Mobile Repair was founded in Round Rock, TX by a diesel technician who got tired of watching customers pay tow bills for repairs that could be handled roadside. With years of hands-on experience across light duty pickups and heavy commercial trucks, we set out to bring shop-quality diagnostics and repairs directly to you.

Whether you're a fleet owner with a truck down on the highway, a contractor whose work truck won't start, or a pickup owner dealing with a check engine light — we show up equipped and ready to work. No waiting rooms. No tow fees. Just straight answers and solid repairs.
