About Us at Smitty & Sons

About Us

Built on grit, grease, and a promise to get the job done right—Smitty & Sons Repair is Lewiston’s go-to mobile diesel repair crew.

Our Story

Smitty & Sons Repair was founded with one goal: to make diesel repair more reliable, more accessible, and less of a hassle for the people who depend on their trucks and equipment to make a living. We know what downtime really costs—lost hours, missed loads, frustrated clients. That’s why we built our entire operation around meeting you where you are.

We’re a mobile-only diesel repair service based in Lewiston, ID, serving fleet managers, owner-operators, and heavy equipment operators across the region. No shop to tow to. No waiting in line. Just fully equipped service trucks, experienced techs, and 24/7 availability when you need it most.

What We Do

From routine maintenance to emergency roadside repairs, we handle everything from engine diagnostics to DOT inspections, trailer repairs, custom modifications, and fabrication work. Our team is trained to work on heavy-duty trucks, RVs, trailers, and construction equipment—on your site, on your schedule, with the tools and knowledge to get it right the first time.

We’re not here to push unnecessary repairs or upcharge every bolt and filter. We’re here to solve problems, earn your trust, and build long-term relationships with the businesses that keep Idaho moving.

What Drives Us

Honesty. Reliability. Pride in our work. These aren’t just buzzwords—they’re how we operate every day. We treat your rig like it’s our own and stand behind every job we take on. Whether you’re broken down roadside at 2 AM or just need a pre-trip inspection before a big haul, we’ll be there—ready to work.

Because at Smitty & Sons Repair, we don’t clock out until the job’s done right.
