I've got a 2007 Ram 2500 early 5.9 diesel Laramie with 155k miles on it. I paid $22,500 about 2.5 years ago and I put 35k miles on it. From what I've seen on craigslist I'm looking at $25k+, maybe close to $30k. I want a 14 and up 2500 and those are $50k plus, at least if I can get good change for my old truck it will take the shock out of the price on the newer one. For example, there was a 06 Laramie 2500 with 166k miles on the local CL for $27,500 and it was gone in a day and a half.
