Sorry to be picky but a friend of mine is in the market for an 04'-06' Chevy 3500 (HD or no), Standard Cab, White, 4X4, Duramax Diesel. That is all I really know. He has an 06' I think but has the 8.1 in it and he travels more so he is looking for the Duramax now. He has a dealer looking for him but hasn't really found anything to match the description because everyone likes thier truck and doesn't want to sell it. It is the type of truck bought in fleet for companies type of truck. Thank you for your time. Have a good day.
