I own a 2006 sd short bed with 6.0 liter diesel engine. I bought it new and it currently has 25000 miles on it. I've only recently begun reading this forum and, frankly, after some of the stories I've read here, I may sell my truck and get a gasser! I've not had a single problem with the truck and I change the oil every 3000 miles or 3 months. I've read of seriously inherent problems with the engine design (sand in the galleries--needs coolant filter; EGR failure (from clogged filter); hopping badly at 40 mph; poor oil filtering causing injector failures; water pump failure. I'm afraid to look any further!! I thought diesel engines were supposed to go hundreds of thousands of miles without problems, but I've seen some major failures and repairs required at 50,000 miles here! I've put the coolant filter on the truck (last week). Should I dump this thing now? I am completely serious here. Thanks!
