The service was amazing. I called on a Friday afternoon and was able to get an appointment for Monday afternoon. Our appointment was at 1pm, they took the RV back at about 12:45. The whole thing diagnostic to completion took less than 2 hours and in our case was covered by warranty. The tech taught us some quick diagnostic things we could do to avoid coming back unnecessarily. And showed us how to adjust the choke as well as gave tips for maintenance. I would absolutely recommend them. They went the extra mile for us. They also allowed us to plug in while we waited for our appointment time. I can't say enough good things about the tech's customer relations, he really took the time to go through everything with us. They are dog friendly. Clean office, clean restrooms. I would send my grandmother there if she needed something done that they could do. read more

Great customer service. Carlos is a Rockstar! Got our Onan 5500 purring and ready for camping trip I'm just a couple days.

We've been in and out of Cummins here through the years and these guys have always taken great care of us and are always concerned that we are up rolling and Road worthy! Everyone has their own field that they specialize in and they all seem to know every aspect it well! The staff is always knowledgeable, friendly and they want you to know exactly what's happening and how they plan on executing a solution! They've always made the right choice with us and I'm sure they will for you as well! read more

See all

We had a very tricky installation and warranty situation and a hard to diagnose problem. Carlos, Cecil and Omar were very professional, knowledgeable and competent. Carlos did an amazing job of explaining what needed to be done and fixing the problem completely. The situation took a couple of weeks to resolve but they stuck with us the whole way. Our generator now runs perfectly. We will come to Cecil and Carlos at Cummins for all of our generator service and repair needs. read more

Took our motorhome in and was told we needed a new engine due to "dusting" in the engine. This was going to cost approximately $45,000. Our motorhome only has 30,000 miles on it! Took it to a different shop for a second opinion and ended up paying only $2,000 to replace 2 filters! read more

After waiting for over two weeks to get my generator serviced, I brought my motorhome in today at noon for my appointment. I was just informed that they are just starting to work on my rig. It is 4:50PM and they never bothered to start until I asked about the status. Can't believe that they never even apologized for their error. Another day wasted because they can't do their job! I just heard, they are not going to charge me for the service. WY to go Cummins! read more

If there where no stars... that is what I would have given. I run a truck across the states somewhat regular and stopped in the get a couple of parts. The lady there, Kaitlyn Summers (sp) was the rudest, non cummins educated parts manager I have ever had the unprivileged to encounter. Talk about a lady with an attitude. I gave up, order my parts online without all the mental and verbal junk she was so quick to shove my way. I also stopped into a different cummins in the state and that feeling I had was a common thread for that lady. read more

Dear Owner, Hello, my name is Dave Flowers. Very recently I flew from san Jose to Denver to retrieve an RV repaired at your business. The repairs included the installation of a new engine. The friendly crew assured me all was well despite requiring a jump to leave the place. Immediately upon entering the interstate I noticed the voltage regulator pegging and the temerature gauge hovering at 220 degrees. I called and spoke to Gil who expressed concern and offered to call back after speaking to Mike, the floor manager. This never happened. I parked the RV in Lafayette for the night and in the morning it would not start. I located and purchased a heavy duty battery and installed it. After repeated attempts I realized there was no fuel at all in the tank. I had made it this far by sheer fortune. The guys had virtually emptied the tank running it on the dyno! 5 gallons of fuel and it started. Still, no return calls after several discussions with both Gil and Mike concerning the overheating problems. I drove to a local station and purchased another 25 gallons of fuel and again had great difficulties starting it. I got it going and headed north on the 25 interstate to the 80 west. The voltage was still pegged and I called yet again with the same promise of a return call. I turned on lights, fans, and all things electrical to draw the current and reduced my speed to 55. This helped and I made it 41 miles past laramie,Wyoming when the temperature gauge spiked while going up a grade. I lost power, saw white smoke from my mirrors and pulled it over where I shut it down. Now, 10,000 dollars later, I'm stranded in laramie with an overheating issue and a fuel leak that coated the engine with deisel. I trusted your crew and as of now think this is just a series of unfortunate circumstances but the fact that you allowed me to leave with a dead battery and an empty tank suggest a certain negligence on the part of the mechanic. This can be determined by further investigation in the coming weeks. I will share results as I receive them. Flying back to san Jose, homeless once again by fate and circumstance. All I ask is that you be fair and honest with me. Sincerely, Dave Flowers read more

My appt was at 10 and the tech was up at 10:30 to tell me nothing was wring and they charged me $350 diagnostic fee. This place is horrible. They hate small business and overcharged me. They never have an answer for anything. I need to find someone who services Onan's in Denver and tjis these RATS to big fleet companies. I would never buy Cummins brand again. Too much drama involved just to get an appt. $350 diagnostic fee for 30 minutes. Rip off. They didnt tell me their rates. Last time there was no fee and cost me $80 for an oil chg. They just tried to charge me $700 for oil chg and maint. These are more corporate white men sticking it to hard working Americans! read more

Pulled in to Cummins in Henderson in a Winnebago Trend with a Generator that would run with no output. Intimidated being such a small guy in a land of giants but they were very helpful and fit me in an hour and half later. They found a circuit breaker that I had missed (generator is up under the chassis). They charged me $139 for the service and ran the system through a series of checks to make sure there wasn't an causative problem. In a world that lives at $174 an hour I was not displeased. read more

If it were possible to give this establishment a zero star rating I would have. We have been motor homing for over twenty years and we have NEVER had a worse service experience. We made service reservations three months in advance and then followed up three or four times to make sure they knew what we were coming in for. The service reservation was for 7:00 AM. We had to drive 500 miles to get to the appointment and get up at 5:30 to make the appointment. When we arrived the service advisor acted like they never heard of us and did not understand what we wanted done. We did not feel good right away. We decided to go to breakfast and left hoping that the service department could rally and get things done. We must have been out of cell phone coverage because we did not receive any messages from the service manager. When we discovered the message (10:00) we called immediately and the service manager had a few questions about what we wanted done, one of which was just routine LOF service. He then told us that it was impossible for them to complete the service that day despite the fact that we made reservations three months in advance. The service department should have started the routine service and at least got that done. We arrived at Cummins at 11:30 and our motorhome had not moved one inch since we parked it at 7:00. Ridiculous!!!!! We then asked to speak to a manager and were told that the manager had the day off. While the cat is away the mice play. NEVER GO TO THIS SERVICE ESTABLISHMENT....EVER!!!! read more
