A 2006 Duramax 4x4 3500 required more maintenance than any truck I've ever owned. The GM was the best riding and most comfortable truck I've owned. But you can count on front end, steering, water pump and Ujoint problems. We do all our own wrench pulling and a Duramax is a night mare to work on. We have 3 older Ford diesel trucks and 2 Ram trucks a 11 and 13 year models diesels. Once we deleted the Ram trucks we've had no issues besides water pumps. Ram has a recall on the water pumps. There all good trucks but no more Duramax trucks for us, the front ends are to light duty for how we use a truck.
