In the short time I have had my truck, I don't see any 'value' in one year over another.... just personal preference in style. If you are going to keep it bone stock, then the oldest one with the most factory accessories is the most 'valuable'. I am obviously not a purist (just see my build), and I don't give a rats a#$ about the resale 'value' of my truck, I just built it to drive. I want as many modern features and comforts as I can afford to put on the truck.... does that make it worth more or less? who cares, I am the one that has to drive it.
