Regarding the use of diesels in Chevy cutaways, our school district added a bunch of Chevy 4500 micro buses with the duramax diesel to the fleet this year. Looks like they are down sizing from the smaller convential bus body units mounted on class 5 or 6 International and Freightliner chassis.
Regarding the derating of duramax diesels in these applications (if true), Dodge did this as well with the Cummins engines in their pickup truck applcations when they were first introduced in 1989 as the 727 and A518 transmissions couldn't handle greater levels of tourgue these enginse can produce. It wasn't until transmissions were developed that could handle the torgue that power ratings were significantly increased.
As to the use of diesel engines in class c applications, I would think there would be very limited demand since the upfront costs are so great (engine option costs) and maintenance costs are higher, with the only real benefit being greater fuel efficiency, not a big deal for those of us who only put about 5,000 miles a year on the unit which I suspect is the norm.
Regarding air bags, I would not be without them. We ordered our unit with this option and they definitly soften the bumps on the road. The ride becomes much more jarring when they lose air.
