To weigh in on the lower hp Duramax issue, just like Ford that engine is detuned for van/cutaway applications. This is likely because of limitations on cooling systems and/or intercooling because of the physical configuration of the van chassis. In pickups, all of the diesels are running at extremely high power outputs for the size of the motor, and it takes pretty fancy engineering to keep these motors running reliably and cool. Both Ford and GM have had some growing pains getting these issues worked out, i.e. Ford 6.0 issues and Duramax LLY overheating.
I would imagine that a main reason for very few diesel class Cs, both Ford and GM is that the detuned diesels offer little or no performance advantage over their gas counterparts and mileage advantage is negated by the extra initial cost. Not trying to start a gas/vs diesel war, it's just my opinion.
On a slightly related note, I would imagine that GM will start selling many more chassis to emergency vehicle builders, since they are the only game in town if one wants a diesel powered 14K GVWR chassis.
