I bought my Cummins and it came with a Dodge frame and cab.
That's almost how it happened, but I do favor the Dodge family.
I bought my '05 Ram 2500 5.9L Cummins before I even dreamed of a trailer let alone an AS.
If something happened to it, I'd look for an '04-'05. The engine is using the High Pressure Common Rail fuel delivery system, these run significantly quiter than the earlier fuel systems, and I do not have any issues with it 90K later.
Enjoy and good hunting.
