I needed repairs done to the radiator on a 20year old motorhome. Most shops I had been calling eather wouldn’t work on a motorhome or wouldn’t work on chassis issues. The guys at Modern Diesel had no problems fixing my issues and working with me on my timeline for the repairs.

Starter on my F250 died on me without any warning. I called Modern Diesel and they said they could get started on it right away. Once I got it towed in they started working on it literally within 3 minutes, and a couple hours later it was finished, for a pretty good price too. I am so grateful. These guys are awesome!

After going to several diesel shops, i called this place. I explained the issue over the phone and he told me what he thought was wrong with it and guess what… He was right!!! Blew my mind. My issue is fixed. It wasnt what the other shops claimed it to be. So happy with this place. Chance is great, knowledgeable, and explains things in ways for nonmechanics to understand. Definitely recommend this place.

Kerry and the techs at Modern Diesel really took care of me on this one. A two day turnaround on diesel repairs is unheard of. So happy they got my work truck back on the road quickly. Will definitely be using them in the future!
