Some say the Dodge chassis is merely a shipping crate for the Cummins engine...
To be fair to FCA, I do think their newer trucks are whole lot better than their older ones ever were. Better build quality, better designs, better outsourcing for many components (Aisin, Borg Warner). Heck, their gasoline Hemi engines are pretty damn reliable and I'd have no problem putting 200k miles on one and treating it the same way I treat my Toyota 4.0l v6. I see very little quality gap between the big 3 (Ford, GM, FCA); Ford perhaps has slightly better quality on interior components, but overall all 3 make good trucks IMO.
But when FCA decides to put an Italian-built 3.0l diesel into its mainstay 1/2 ton, an engine which seems to have had internal troubles (never-mind the emissions) from the very beginning, and then insist on using that same engine for the sacred Jeep platform, I do start to question the company's decision-making. I think the Italian ownership of FCA is letting their national pride influence their choice of engines. They'd get a whole lot more buy-in on the diesel concepts for 1/2 tons and jeeps if they went with a proven brand like Cummins...at least that's how I see it.
