PACrew, how do you search? The best method I've found is searchtempest, I type in all the years I want then "or" it with crew cab and ford. Export the RSS file to google reader so I can scan all the craigslist sites across the country in a half hour or so.
PS- I grew up just south of Butler, PA and my parents and most of my extended family still live there. Can't say I've seen too may of these trucks around there!
Search Tempest. I use the craigslist search, get all the results instantly. Sometimes the site gives me problems, especially when I use the ebay search on Search Tempest, it usually wont pull anything up, even though there is a crew listed in ebay's main site. I have never been to Butler but close by a few times, especially Allegheny National Forest area. I wanted to transfer to Army Corps of Engineers at Tionesta a few years back, but it didnt work out. And you are right, unfortunately there are very few trucks around here
