Boy, that sucks! One ramification I see from that is future HD engine development (or lack thereof)...previously & currently, the 4500/5500 trucks used the same powerplant as lighter duty 3500 trucks (8100 & Dmax, most recently)...but with 1 less model line utilizing a pretty specific & limited powertrain, it just makes it that more expensive for it to hang around...I could easily see GM bail on the 2500/3500 market, and basically hand it to FoMoCo (which does the majority of heavy fleet sales already).
There for a while there was talk of a 4.5L Dmax for the lighter GM trucks (like folks have been asking for for YEARS), but last I heard it was shelved...crazy thing is, it would have provided a significant increase in fuel economy & longevity...guess I'll just have to build my own?!
