The guys are great! Very knowledgeable and took great care of me and my truck! I highly recommend them!

Nate, Tree, and their crew of mechanics are the most competent and honest diesel mechanics in the valley in my opinion. I bought a 2010 Cummins from Lithia and it had nearly every problem that you could imagine with it. I took it in to several other mechanics only to get put back on the road with all of the same issues. I only had to explain verbally what was going on with the truck and Tree was able to diagnose my problems. I run my truck a lot harder than the average guy and they have me hauling and towing up and down unpaved mountain roads with confidence. I have the ultimate work horse now.

This shop and entire crew deserve 10 stars. I have usedthem for years to work on my diesel pusher motorhome, I cant say enough about the experince and knowlage they have, if you have any troubles, go see the crew at RPM first, you will be glad you did

RPM Diesel has worked on our motorhome, and two diesel pickups. They are not cheap but they are very very good at what they do and the job is done right the first time. They are a busy shop but they got me and out quickly. Tree is very knowledgeable and knew what my problem was before I was finished telling him. He grabbed a flashlight and looked at the truck and said I had a coolant leak at the turbo. He gave me an estimate and when the job was done it was 300 bucks less than his estimate. All my diesel work will go to RPM Diesel because they have earned my trust and friendship. Thank you RPM, you are the best!

The guys At RPM took in our truck when we broke down on the freeway near them on our way through to Florida. They squeezed us in and got us back on the road in record time. They were thorough and made sure we wouldn’t miss anything so we could get across the country safely. Highly recommend their services.

Great customer service. Nate and Tree are both super nice and got me in the door with no notice. Wish I lived closer!

Highly professional staff and very knowledgeable. They fixed my work truck quickly.

Great job on 2001 5.9cummings. Great people. Cant go wrong with them. Ill be back.

Motorhome broke down 30 miles out of town. Owner made service call out to us and offered shop for immediate service. All employees were friendly knowledgeable and very professional. Got our fuel pump replaced and also charged our cab a/c while we were there. Excellent job and we plan to stay in town for awhile😍

Great shop! They did a cp3, injectors and fast lift on my lbz. Just got back from a 2k mile haul and had zero issues. I highly recommend these guys and gals. I have found my diesel shop for life!

RPM was recommended to us by another repair shop that specialized in RV suspension systems, Henderson Line Up. I was a little disappointing at first but after having RPM do a whole series of needed repair on our Vintage Discovery diesel pusher MH, Im delighted that we found them. In a time when most if not all cars, trucks and RVs are completely computer controlled finding a shop that can diagnose and repair a 20 year old RV is like finding the proverbial needle in a haystack. The list of repairs we had them do is long and wasnt cheap. But if you own a Motor-home you better be prepared to spend some money if you cant do the work yourself. Im a decent mechanic but know my limits. I spent my career as a Project Manager and Superintendent on large commercial construction projects and in that position you learn to separate those that know their craft from those that are faking it very quickly. This shop has a whole cast of terrific mechanics but the jewel in the crown at RPM is Tree Simonson the Shop Manager. His ability to trouble shoot electrical signal problems is as good as anyone Ive run into in my 45 years in mechanical electrical controls.Not only did Tree and his gang, Ben and Matt, the two mechanics who affected our repairs perform the standard repairs but dove deep into some wiring issues, custom fabricated and adapting a new exhaust brake since the OEM part was no longer available anywhere. The braking on is terrific now. Good work isnt cheap but usually cheap work isnt good. Ive learned it doesnt pay in the long run to have work done by cut rate or marginal tradesmen. So I can say with real enthusiasm, what every your problems are with whatever you vehicle, HD pickup, Motorhome, OTR tractor, earth movers, crawlers, stationaly power plants or HD diesel generators, if you have a machine that needs repairs go talk to Tree at RPM. I can tell you this these guys will be taking care of any future repairs I need on my Motorhome, period. And you can take that to the Bank!

Good, I would recommend them, willing to explain issues and have a lot of experience to draw from, also willing to work into their schedule on short notice

Great experience, professional, friendly, knowledgeable. I highly recommend them.

RPM worked on my boom forklift and did an outstanding job, they really went above and beyond to get the repair correct on some very custom parts. I would highly recommend.

I recently bought a used commercial type rig and needed a full service/inspection done, fixing a few leaks, plus it was having trouble accelerating (acting sluggish). Dropped it off with RPM and had it back in just a few days. They fixed all the leaks, solved the sluggishness, and charged me a fair price. They also were great at communicating progress over those few days. Shout out to Nate!

Staff very knowledgeable. Noticed issues with my truck other places either didnt see or didnt bother to check. That says a lot right there.

My 7.3 Ford developed at large fuel leak at O-dark thirty on a Monday morning while on the I-5. I called them as soon as they opened and they immediately adjusted their existing appointments to get me in. They were great at accomodating my horses and getting me back on the road in about 2 hours. Their over all service & value was outstanding.

Super nice guys, Very helpful

Long story short, they had an opportunity to make some quick cash off my back and they chose to do the right thing AND take a loss by referring me to honor my warranty completely and save me both parts AND labor.That makes me want to get on here and pass the good word out to potential customers and draw that business back in for RPM Diesel LLC. Thank you for exercising such integrity and squaring me away, Tree.

I didnt have any work done here because the mechanic suggested easy fixes I could accomplish by myself to save money!

If honesty and integrity are as important as great service to you, RPM Diesel is a trustworthy place of Buisneses. The Owner is a stand up guy and his team is top notch!

Well I have spent a few thousand dollars at this place getting my truck fixed and they did a good job fixing my truck but the lady that answers the phone is RUDE! And makes you feel like you are an inconvenience to her day. If I am an inconvenience dont answer the phone or change you job! And the other reason I am giving a poor review is because I took the truck in and they said for sure it was going to be a set price and then they went 400 over the set price! Im sorry maybe I am old fashioned and I expect people to keep to there word! But, I paid it not as happy as I would of liked to of been since I was already paying over 3000.00 this was about a month ago. And it took them a week to fix it when they said it would be done in 3 days. And they make some excuse of why they couldnt get it done in time...but 4 extra days. Ridiculous!OK so the new thing is when you say you are Goin to call someone back call them back! And if you have my work truck and TELL ME IT WILL BE DONE that day! Then for heavens sake get it done that day! I can understand if you cant get it done on time then that is fine! But, at least call me and let me know so that way I dont have a friend take me to your shop to pick up my truck and find out then that it isnt done! Serious how hard is it to communicate the situation!

Nate was a life saver today. We are towing a trailer with our Duramax Diesel& stopped @ Valley of the Rogue park for lunch. The truck started & then died immediately. Randomly called this shop &Nate advised checking & bleeding the fuel filter I had changed recently. Worked like a charm! Thank you for your kindness & excellent advise.

Very very helpful guys here.. Definitely recommend

Best prices in town for trucks and quality work you can trust!

I was recently south bound on I-5, and after an overnight stop neat Grants Pass, discovered a huge puddle of coolant under my F-350 6.0 diesel. The coolant looked as if it was leaking out from the joint between the head and engine block; very bad news with this engine. Did some calling around, and several shops were over a week out before they could even look at the problem.Had the truck towed to RPM. They called me a couple of hours later to come and get the truck, as it was done!These guys are a true testament to traditional, honest quality small business practices. They could have taken me down a very expensive repair path, but instead utilized analytics, pinpointed the problem, and got me on my way.What a pleasure to find a business like this! I whole heartedly recommend RPM Diesel.RTS

Great company they always do an awesome job on our rigs. Office gal is rude, maybe she shouldnt work at a place were she has to answer phones. Not good for business.

They helped me order a part and had it the next day, great service. Drop pit-man arm

They got my radiator replaced faster and for less money than I expected.

Knowledgeable, Honest, Reasonable, Helpful.

The guys at RPM fixed a obscure problem with mytruck that no one else could fine got me in and back on the road.thanks Tree Simonson and the guys

The go to place for landscape material. I hope the city doesnt get the property

Took 7 hours to put on a turbo and overcharged for the it! ITS A 3 HOUR JOB! Would not recommend this shop to anyone!!!

Always helpful and they do great work

Had work done to fuel system on a 7.3 ford. Fair price.

Knowledgeable courteous friendly.
