These guys had one of our dump trucks back online in 2 days versus the 3+ weeks and failed repairs from other diesel mechanics. Thanks to Brian for getting us up and running!

Great shop to work with they always take care of us and our trucks and always work with us instead of against us which is great for a shop. Brian took great care of our dump truck to fix the power steering that needed to be done. I would recommend this shop for anyone who needs heavy diesel mechanics

It is so hard nowadays to find a repair shop you can trust. Well, our first ever experience with the folks at Smiths Heavy Repair could not have gone better. Our truck was stuck at an intersection, unable to get into any gear. I found them on a Google search and called them. VERY friendly lady name Paulee helped me out on the phone, got us set up for mobile service and dispatched her truck. Told me about an hour but I'm pretty sure they got there in less than 45 minutes. The tech, Josh Smith, did find the problem, patched us up enough to get to their shop and finished the repair properly in the shop, and got us on the road. If you are searching for a repair shop in the Pocatello ID area, look no further! These amazing folks have mobile service, in shop service, and access to a local tow company. They are new, but genuinely interested in helping at a reasonable price. And do yourself a huge favor ... put them on your Trusted Shops list. I did. Roadex Services Ltd., Saskatoon SK Canada

We had a reefer engine that ran out of fuel and sat for days, requiring a repriming of the diesel reefer motor. On the day, we were directed to come by, we did need to wait a little due to being short a few mechanics on that particular day. But the quickness of their response was totally reasonable and actually very accomodating due to the circumstances. Our reefer engine was very stubborn, but staff was able to get us back running rather quickly, and for an exceptionally reasonable price. Would definitely use their services again, and highly recommend!

My hat goes off to Paulee and Chris and the friendly mechanic who took care of the problem. THANK YOU AND HAVE A BLESSED DAY
