DRH Mobile Diesel Repair LLC

I’ve never let anyone touch my trucks but me, ever. I’ve always done all my own work, but this time I ran into an issue I just couldn’t figure out. I called the dealership and a couple other shops, and none of them inspired any confidence. Then I came across David and his mobile service, and I’m honestly blown away. I’ve got a Chevy Duramax dually that was throwing all kinds of codes. I was chasing my tail trying to diagnose it. David came out, and like the mad scientist he is, he figured it out without even relying on the codes. His knowledge is on another level. He’s smart, professional, and clearly takes pride in his craft. I’m truly impressed, and that’s not something I say lightly. I 100% would use him again. If you need someone who actually knows what they’re doing, call DRH Mobile Diesel Repair. Highly recommended.

David at DRH Mobile was accommodating, quick and accurate. He got us back on the road within a day for a fraction of what 2 other places were going to charge us and it turns out those 2 places were wrong about their diagnosis of the issue anyway. We won’t be trusting our vehicles to anyone other than him in the future. Highly recommend!

David came out and got frank the tank 04 f550 6.0 back up and running. Hes very Timely, knowledgeable, and fair priced. I was at work all day. I left the key at home, he did the work and emailed me an invoice and tookoff. Definitely would recommend to anyone and everyone

I called David and told him that my truck wasn’t holding coolant, going through a gallon a day, he came right to my house within the hour and fixed the issue, he was super nice and knowledgeable! Definitely recommend him to anyone needing repairs!

10/10!! I can not say enough good things about this company. I had a massive electrical failure in my diesel that he was able to diagnose and fix in less than 24 hours from my original phone call. Fast, prompt, honest and professional. I have had a lot of mechanics before and he was by far the best I’ve ever experienced. I will use him for all of my needs from here on out.

Extremely pleased with my experience with DRH Mobile Diesel Repair. When my check engine light came on, I imagined the worst. David diagnosed the problem and removed the rat nest in the engine compartment in my Winnebago Jouney DL, repaired the wires eaten by the rats and had my engine purring in no time. David was prompt, is very knowledgeable in what he does and I consider fair in price. So service was great and David is a good person, hard to find nowadays. Highly recommend.

Don’t listen to any of the positive reviews on this page, I had hired this “mechanic” for a drop kit and several complications occurred. First off, I had him use a custom kit, which he didn’t read the instructions for, resulting in a four inch drop instead of a two inch drop. This was because the kit needed it to be at OE height with the rings properly installed, which he did not do. After I had called him back, he wanted to charge me an additional $200 to fix the mistake that he had made, and also had an attitude. So, I needed another mechanic to come and fix his mess, which I then found out that the emergency brake line is wrapped around the shock (see attached images.). He also left the ball joint bolts loose, where the driver side one was bent and the stud broke off from him being rough on it, although he had also messed up the passenger side one as well, which we need to replace. Additionally, the parts were still wrapped in plastic. Considering that the vehicles bolt popped off when the mechanic examined them, it could’ve been a serious safety hazard to where my truck could’ve needed to be towed. All n all, don’t go to this quack of a “mechanic” for your lowering or any other services before you spend money having to fix his mess. I’m sure even you could do better with just online videos.
