Mine's an '06 factory ordered QC LB 3500 dually. There is only 65,000km and 2100hrs on the truck. My only complaint is how it breathes. The air box/filter are a joke. Way to much restriction. I use a K&N drop in filter in the summer and clean it regularly. The other little issuse is the blow by tube off the crank case. This sometimes freezes off and creates a vacum then thaws out dumping oil on the gound ( about half a cup ). It has done this twice since new. Other than that it's been a really good and dependable truck :d
haha.. the good ole cold start puke.. mine used to do that before i got my injectors done. I replaced my air intake with a AFE stage 2.. theres a big restriction in the intake tube to the turbo.. put that apart and you'll see what i mean. :d
