Just some really good people working over here above and beyond! Ask for Ted he will help you out! Thank you guys!

On the phone scheduling we were very impressed, we were able to stay on site for 7:30am appointment. We were only there for annual service. Now for reality!1. We had to call office at 7:50 to make sure we werent forgotten, was told our guy was on the phone and when he got off, theyd let him know.2. The tech showed up and didnt really care if we were there or not. When asking questions he shrugged his shoulders and acted like we were idiots for asking. When asked how long he thought it might take, again shrugged shoulders and would call when it was done. We got at least half a day. Were in a motorhome and have reservations down the road, if we were going to be late or not make it that night, I needed to call. Needless to say, we left our home, not feeling very confident.3. We return to Cummins at 2, can we help you? We explained we are the people with the motorhome being serviced. Ok, the last door on the left is the waiting room. Fine! It would of been nice if someone offered to check on it, let us know how much longer, no big deal, just a courtesy.4. We received the bill, the gentleman that gave us the bill really didnt want to go over with us. It was a bit more than we anticipated, but not surprised. Almost $2000 for a service! Almost $1300 in labor, $265 an hour!!!!! WOW!5. We own a Country Coach, not a Holiday Rambler! Sorry Holiday Rambler, but thats an insult!!! This Cummins knew nothing about our coach!NEEDLESS TO SAY, WE WILL FIND A DIFFERENT CUMMINS! Weve been pleased with other Cummins, so its not the company.

Top of the customer service relations. Everyone is so nice and friendly. The mechanics are willing to come out front and discuss you truck problem when you get stumped doing your own repairs and need some helping advice. As with all Cummins shops they are quite pricey. But you are getting Cummins Certified Service and OEM parts. That makes the added price acceptable in my book.

Had good experience getting parts through parts department for my Onan. Getting it fixed was different. Was told needed water pump which took service dept a week to get and longer to install. Now have major water leak and need reschedule an appointment for them to assess ? Not best customer follow up.

I cant say enough good things about this place. They were honest, reliable, accommodating and friendly. Their follow through was top notch. My husband and I were boondocking out near Alcova when our generator when out! We called this place and the next day we were headed that direction. They isolated the problem, got us fixed and the part that impressed me the most is they had very strict Covid-19 rules for the safety of everyone! If you are in Wyoming and need help, if you called Cummins in Gillette you will be taken care of!

Professional Con ArtistsTried to charge me $411, for removing six screws and telling me my generator on my horse trailer was locked up and needed replaced with a $4000 one and when I said Ill wait to get one they drummed up some BS charges and expected payment. They didnt even put it back together. Will never use them again they are Crooks!!!!!!!!

Thank you Alex for working us into your busy schedule over a holiday weekend and thank you Brian for doing such a great job trouble shooting and repairing our generator. Things are working perfectly and we enjoyed our stay at Camp Cummins...lol

It’s been a year, since these guys replaced defected turbo on my KW. Still pulling strong. Thank You!

These people are top of the line! Great customer service. Megan went out of her way to deliver a water pump to us in Buffalo. She made the day!

Very helpful I just wish Google would fix it where it says open 24 hrs change it to 6 to 6

Excellent customer service!! Wish I could give more than 5 stars! Outstanding. Peter and Tyler were awesome!

Took my son over there to get it injector pump for his truck they was real helpful real nice and the place was clean

Alex has great customer service. Went above & beyond to make sure we had all the information needed to maintain our generator.

Service was excellent and we were able to park on their RV pad with electric HU for the two nights it took to get our generator repaired. I would give them five stars if Cummins wasnt so overpriced.

Huge shop, good people. Rocky Mountain Cummins is a huge business and they seem to care about there customers.

Very professional staff. The mechanics will even come out to service desk to help you solve a problem if you are having trouble DIY your repair.

Went to visit with an old friend, very good visit.

Great service on my generator. It was diagnosed and repaired in no time at all.

I had some general Cummins questions and other questions regarding shipping options. Jessie not only gave me the answers, she even helped me navigate the warranty information available conveniently online. Thank you!

These are the professionals. Accomidating, knowledgeable, helpful.

Was head to this faculty to get parts for my generator when we list our brakes on our FREIGHTLINER, limped into the faculty and talked to service manger, he checked under the truck and found a brake line fitting loose. He tighten it backup and we had brakes again. Back on the road.

Friendly help and had everything I needed

All of your Cummins needs in one stop
