2008 Ram 2500 (6.7L Cummins) — Should You Buy One?

Typical asking price: $16,000–$30,000. There are 3 high-severity known issues you need to know before handing over a check.

Kestrel Take

The first years of the 6.7 Cummins traded the bulletproof simplicity of the 5.9 for more power and an emissions system that clogs. The engine is strong; the DPF, EGR, and the weak 68RFE automatic are the recurring bills. Buy the manual or a well-maintained emissions system.
