So ya the wife and I have been going back and fourth. Its over our budget but it looks like this guy might need to sell this ASAP. The holy grail of trucks I mentioned before?? HERE IT IS!! This is the one. This thing doesn't need anything at all. I'm like a kid at christmas over here.... What do you guys think for a price on this?? $14,800 is high Gold book, and between average and high with NADA. If I could get this truck for $11,000 to $12,500 I think I would do it. give me some input!
