I'm not sure if it has truck prices, but there is a magazine publication called "Old Cars Price Guide", which is available in good newsstands, like a Barnes and Noble Bookstore. It is organized by car year, make, and model, and gives five price categories, which are based upon recent car auction activity. It tells you how to select your category of condition "1" thru "5", based upon approximate condition which it details out. If your car has all matching numbers (the engine etc., has matching numbers to the cowl tag in the engine compartment) you probably can get a premium in addition to the price it shows. I have used the publication for many years to see when I should adjust the value of my classic car's "actual stated value" insurance policy, and have never been turned down by my insurance company as to too high of a value being imposed... it's a paper magazine, so you don't have to use your computer contrapshun, maybe just spectacles for bad eyes will be the only technology needed......

Without more Info. like options,and pictures to see the real condition of your truck,giving you a price range would be unrealistic,and not fair to you ending up with false information. I wiould love to help you ,but would need the above Info. to do so.
