dieseldvm 5pts not usually a gm fan, seem to be last to party when comes to innovations. however am very interested in colorado/canyon pickups with 4 cyl diesel. can't quite figure out gm's distinction between chevy/gmc. like the size, smaller than 1/2 ton yet plenty capable of serious hauling and towing. with diesel 30 hwy and 7k towing should be very doable. like ram 1500 diesel but bigger than i want.
