if you are into your truck like most of us are it is worth having and if you intend to buy another truck some day it has all of the info to decode it and make sure it is right before you buy it or at least tell you what has been done to the truck and they are getting really scarce each dealer ship had at least one some had a couple depending on volume of sales and staff. I am not trying to talk you in to it just laying it out for you as some people I know and have met over the last 25 years doing this stuff had never even seen one or new they existed.
