This is by far the greatest and most comfortable truck ever made. And if power and performance are what you want then this is the truck for you. The only trouble I had was with the injectors and luckily they were covered by the LB7's extended 7year/200,000mile warranty. Other than that I have never had trouble with this truck. Plus the aftermarket for Duramax's is so wide open to your imagination.

Best vehicle I have ever owned. Still smooth and powerful after 150,000 absolutly trouble free miles. Ford and Dodge probably have as good an engine, but no way can they match the Allison/Duramax as a package. I used to trade trucks every year, but I still enjoy this one so much I want to see just how long it will go.
Both light- and heavy-duty 2500s sport new torsion bar front suspensions. Light-duty models now offer optional traction control and standard child safety-seat tethers. Heavy-duty Sierras are completely redesigned for 2001 offering two new engines and transmissions, bigger interiors and numerous other improvements aimed at buyers looking for a "professional grade" truck from GM.
