Looking for a dually

[spareparts]

Friend of mine is looking for a dually. He had a real nice 2000 Chevy that was totaled when an old man pulled out in front of him. Luckily, no one was hurt, but his truck is totaled. The insurance didnt pay that much, so he's in the market for another truck. Preferably a GM, gas or diesel. Must be 4 door. Prefer a dually, but a 4wd 3/4 ton or 1 ton would work. Age is not as important as condition. He;d actually like to find an older truck(pre 1990) if it was in decent shape. All the new stuff is way out of his price range. If any one runs across a nice one, let me know and I'll pass it along
