  Went in for a suspected bad EGR valve. Aaron was the technician and was able to determine that it was a bad air density valve instead. Aaron then went over the engine and also checked and cleared all error codes. He showed me so many things related to preventive maintenance that all other technicians would have never bothered about. Aaron is absolutely the best and most personable Technician that I have ever met. Aaron made this a very productive and pleasant experience. He saved me money, got us on the road in record time and suggested a better route home. I am so glad to have met the people at Cummins in Knoxville. Dave on the desk was extremely kind and helpful and assigned Aaron to our problem. Thank you all.

  Friendly but way overpriced. Second failure of Onan generator fuel pump in 20 hours of use.

  This place would get 10 stars if we could. We had a check engine light come on in our motor home while heading towards Knoxville. We called and Theresa said to come on and they would send someone out to diagnose our issue. We pull in and Aaron comes out to do the diagnosis. He is able to fix the problem and we were back on the road in a couple of hours. They were so kind and professional. They really cared and took care of us. Thank you Theresa and Aaron. Good people!!

  Went in to talk about Onan generator service and parts and Damon on generator side was very professional and helpful. Labor rate is high but that's not his call.

  Great service and knowledgeable people. Had problem with cooling system on my Motorhome and they repaired it to my satisfaction . They are very busy so don’t expect to get your problem fixed immediately, or cheaply , but it will be done correctly.
