let's see if this works posting my search links.. this is how I found both of mine.. keep tabs open in separate browser and refresh daily or more..
simple search terms should catch all of them unless misspelled and the strays are minimal enough to keep the hit count down to one page..

you get the idea.. add all the major cities you're willing to drive to or ship from and check the boxes for surrounding cities until your search results overlap..
you'll go through all of the usual mixed bag of craigslisters.. some really cool folks and some super flakes.. gotta weed through them though when you're on the hunt for something getting kind rare..
lots of 2wd but 4wd results are limited and even fewer 3/4t 4wd..
used these too but lots of bogus listings and emailed and called on a few that were either sold two years ago or never heard back from anyone
