If I ever encounter the misfortune of having a Cummins problem I can't personally fix, I will take mine to Rocky Mountain Cummins in Billings, MT.
Fortunately, so far the only reason for going there is to buy filters, mud flaps, and a barring tools.
I used to take my older dodge to the Rocky Mountain cummins shops, but after they closed the Great Falls store, I had to follow their mechanics to their own shop. That is what Rocky Mountain Truck Center is, a bunch of displaced highly trained diesel mechanics who didn't want to move to stay employed with Cummins.
When I move from Montana to Alabama next month, I will back to having cummins repairs performed by cummins dealers again like Rocky Mountain Cummins in Billings. So long as I live in Montana or am here visiting, I will stick the guys here in Great Falls, Their labor rates are less than the Cummins shops, and offer the same training and experience behind them.
I also have them maintain my Detroit engine in my Volvo as well though, so I have a one stop shopping deal with them.
Overall, any Cummins dealer is beyond the scope of a dodge dealers parts installers, I say parts installers because they do not know how to troubleshoot, they just pull and replace parts until something works. No wonder most of Montana buys their dodge diesels from Dave Smith Motors in Kellogg Idaho.

At least their honest about it, Here's your truck, sorry we can't handle the Cummins repair, take it to Cummins, if its under warrantee, they send your truck there for you.
