I bought this truck in August 2001 with 5,500 miles. Now has 152,000 miles. Engine is 8.1 liter with Allison 5speed. Don't think I'll ever part with it. Gets about 14-15mpg empty if driven sensibly, and about 10mpg pulling my 35' 5th Wheel that empty weight is 12,500#. And this truck is a 4x4. With exception of a couple minor sensor issues, It has performed flawlessly.
