2019 Ram 3500 Cummins — Should You Buy One?

Typical asking price: $40,000–$58,000. There are 3 high-severity known issues you need to know before handing over a check.

Kestrel Take

Maximum capability — the one-ton Ram 3500 with the high-output 6.7L Cummins puts up class-leading tow and payload numbers, in a genuinely plush cabin. This is a serious work truck, so the questions are serious: emissions-system health, whether it was deleted/tuned, and how hard it was worked. A documented, stock, un-abused 3500 Cummins is about as capable as a pickup gets; verify everything.
