I found a truck I might be interested in, and want some opinions. The truck in question is an 01 2500 Quad Cab 4x4 with the 8 foot bed. It's got the HO engine with the 6 speed manual. It has 23,000 miles on it. The asking price is $20,000. What do you guys think, as I don't really know what these rigs go for. Thanks
