my concern on a new diesel is "will it hold up over the long haul"?
The speaker mentioned a 3 year payback, but if there is many repairs (we all have heard or had the invoices on repairs of new designed diesels) those paybacks can disappear quickly.
I too want to hear more details about the engine itself. Given the equity that Cummins has built up for Chrysler in their p/u's, it would be foolish to run with a shakey (pun intended) diesel. I suspect this engine probably has been out in Europe for some time. If I was signing on the dotted line for this, I'd be taking a very close look at the emission warranty - but I'd say the same about any modern diesel, as many manufacturers can now get away with a surprisingly short warranty.
