I would say that it is not a bad idea. The truck is amazing. I had ordered a MY 2006 and was just about to take delivery of it when I found a 2004 with 6K miles on it just last week. It was over $13K less expensive and seemed too good to pass up. The only issue that I see is that dealerships are still not dealing much on the 4.8 and that is what made me change my mind on the deal I made. Some dealers were not willing to deal at all. I advise that you look around at nearly new 4.8's before deciding what a good deal on a new one is.
