Smokin' J Diesel and Automotive Service

Our Story – From Mobile Repairs to an 8-Bay Facility

When we first started, we knew truckers and fleet operators needed a reliable, no-nonsense repair service they could count on—day or night. Armed with just a single service truck, we hit the road, providing on-site repairs and emergency breakdown assistance.

By 2022, the demand for our expertise led to the opening of our two-bay repair facility, which quickly expanded into an 8-bay, full-service shop. Now, we offer everything from alignments to engine overhauls, still keeping our mobile service and roadside assistance available statewide.

Today, our reputation is built on honesty, expertise, and a relentless commitment to getting trucks back on the road—fast.
