Found a decent priced 04 QC 3500 dually 4x4, it has 134,000 miles on it. Didn't test drive it yet but had a question, the truck was cold but started up nice, but while in cold idle it's emmitting a small amount of white smoke, a little puff when you hit the pedal, is it because it's cold or there's something wrong with the motor. The exhaust also smelled funny like bad diesel fuel maybe? Mind you i have had my eye on this truck and it's been sitting on the lot for at least 7 months, mind you when I say cold I mean the motor wasn't warmed up and it's only about 40-50 degrees outside
