Awesome guys! I travel around the country and know it’s hard to find a good mechanic, and they are one of the great ones. I needed some urgent front end work done, they got me in quickly, were very accommodating to my situation, and got me safely back on the road. They worked skillfully & patiently. Didn’t try to upsell me, but took the time to give me honest advice. I feel beyond lucky that I stumbled upon this place, I would absolutely return if I’m ever in the area, and would recommend it to anyone!!!

FRAUD!!! After working on our first work truck we were charged $1300 to fix the AC, AC was not fixed yet. He charged us anyways. We had a second truck also AC, not working along with the engine brakes We gave him a opportunity to come down and fix the first truck and address the second … He worked on the Friday before Fourth of July July called it “holiday pay” Gave us a big laundry list of the things that he worked on and said everything was “good to go” Charged us at an additional $600 part deposit sent us a $1700 bill We were hesitant To pay the bill due to the 1st issue so we check to see if his work was done properly. Nothing was fixed. I repeat nothing was fixed. AC blowing hot air, Jake brakes not working Zac is a liar and charged our company $3600 for NOTHING

Zack was wonderful, we were having issues with our truck while heading from Idaho to northern Montana, he made a timely service call, let us know of close by RV places to park while the truck was in the shop. He worked tirelessly on a Friday evening/Saturday to identify what was throwing the codes and get us back on the road as quickly as possible. He was so thorough and kept us updated on progress.

I had a great experience with this diesel mechanic. I was working out of town when my truck needed repairs, and he handled everything for me without any hassle. He kept me updated on what was going on, explained the problem clearly, and got the truck fixed quickly on a Sunday

Highly recommended! Quick response. We needed repairs on our Class A motorhome while we were on a 1200 mile road trip. Zach drove to our campsite, brought the parts and fixed our rig on a SUNDAY! He was professional, highly skilled, and pleasant to deal with. 10 out of 10!
