          Annual Cummins engine service and Onan Generator service. It took about 5 hours. They told me the batteries were weak so I said replace them. Probably could have gotten more time out of the old ones but I didn't want to take a chance. They have a nice waiting room and also overnight parking with at least electric. Shop is very clean. I would use them again. They only currently do engine and generator work. No chassis or other RV repair.

          Our generator was not working. Cummins did a great job in diagnosing the problem and fixed it the same day we brought it in. We are very happy with the way Cummins handled our situation.

          Oil leak in engine compartment. Work to be done under warranty. We arrived at the facility the night before and were able to plug into electricity and spend the night at their site. They came out promptly at 7 am to pick up the coach, directed us to the customer lounge and said they would contact us there when they were done. We asked at the desk around noon and they said it would be ready when they finished the paperwork and said they would get us. After 2pm we again went to the desk and they acted like they had notified us long ago the coach was ready, but they had not. About 300 miles east the oil pressure was dropping so we stopped and found the oil leak much worse than before and we had to add a gallon of oil and called the Cummins place where we were headed to fix. The facility was nice, but they obviously didn't fix the problem and their customer face could use improvement.

          Installed new starter on my Onan. A little pricey but was very good. Got there at about 6pm they took the information and then showed me where to plug in for the night it was there 2nd day at this new location. No appointment necessary in fact they don't make appointments just show up and they will get right on it. They took me in the next morning at 7.
