About Roadside Repair LLC
Serving Flagstaff and northern Arizona since 2001, Roadside Repair LLC gets drivers, RV travelers, and commercial fleets back on the road fast.
Dispatch is answering
Day or night
David Sims started Roadside Repair LLC in 2001 with a truck, a set of tools, and a commitment to answering the call no matter the hour. The idea was simple: when a truck goes down, someone needs to answer the phone and show up. What began as a local operation serving Flagstaff has grown into a heavy duty roadside assistance and mobile truck repair company that fleets, owner operators, and everyday drivers across northern Arizona rely on.
Over the years, the work has grown to match the terrain. Interstate 40 and I-17 run through our service area, and so do dispatchers looking for commercial truck repair they can count on when a rig sits idle on the shoulder outside Winslow or Williams.
Today, Roadside Repair LLC handles everything from a flat tire on a family sedan headed to the Grand Canyon to tractor trailer repair for a fleet running freight through Flagstaff overnight. The equipment has changed since 2001. The commitment to showing up hasn't.

We run this business the same way David started it in 2001: answer the phone, get there fast, and charge a fair price for the work. Every call, whether it's a stranded RV traveler near Sedona or a fleet manager coordinating fleet roadside assistance for a truck outside Tuba City, gets treated the same way.
What We Offer
Roadside Repair LLC isn't a call center that dispatches whoever's closest. David Sims and his team have spent over 20 years learning the roads, the weather, and the specific problems that come up on this stretch of Arizona.
Here's what that experience means for you when you call.
Since 2001, our team has handled everything from mobile diesel repair and diesel diagnostics on semi trucks to simple lockouts on family vehicles. We run JPRO diagnostics and Pro-Link diagnostics on modern engines, so commercial truck repair starts with an accurate read on the problem instead of a guess.
Our service area stretches from Flagstaff to Sedona, Cottonwood, Winslow, Williams, the Grand Canyon area, and communities on the Hopi and Navajo reservations, all the way south to Ortez Junction. Wherever a truck breaks down within that range, we can get a technician moving toward it.
Our trucks carry what's needed for truck axle repair, trailer axle repair, and mobile axle repair jobs that shut down a rig completely. We also carry tools for roadside tire service, spare tire mounting, and commercial truck tire service, so a blown tire doesn't turn into an overnight delay.

Our process
Every call starts the same way and ends with a vehicle back on the road. Here's what happens between those two points.
When you call, we ask what's happening and where you are, whether that's a semi truck roadside assistance call from a fleet dispatcher or an RV roadside assistance request from a family pulled over near Munds Park. We figure out fast whether the fix is fuel delivery service, a truck lockout service, or a full truck breakdown service.
A technician arrives equipped for the job, whether that's emergency fuel delivery, mobile commercial truck repair, or mobile trailer repair. Most issues get resolved right where the vehicle sits, without a tow.
Once the repair is done, whether it was mobile RV repair, mobile semi truck repair, or truck and trailer repair, we make sure the vehicle is safe to drive before we leave. For tractor trailer roadside assistance calls involving fleets, we keep the dispatcher informed the whole way through.
What drivers and fleets say
Finally a real true mechanic. Not a part changer. He repaired the problem and it was in a difficult place and he corrected what our company mechanic didn’t do or care
I had a bearing failure on my RV about 1.5 hours north of Flagstaff. It required some roadside spindle repair, and I received some maintenance advice. Excellent service and it’s running great.
Blew a tire 8 miles out of Flag. It messed up the electronics, Dave showed up and went above and beyond to help us. Spent 2 hrs trying to solve the issue after getting the tire sorted. Dave was super friendly and professional. Cant speak highly enough of the dude. 10/10 service. Five stars. Thanks Dave!
