Typically, Auto Trader is full of higher priced rigs. My dealer friend refers to it as "the book of dreams". Craigslist is going to yield the bargains, if there are any. Either "All of Craig's" or "Search Tempest" let you search a bunch of areas at the same time. You can get fairly specific on your requirements, but not as specific as autotrader. I will also put in the good word for KSL if you are able to shop the Utah (and close to Utah states; Wy, Co, Id). It is a great place to find trucks. You can get very specific on their searches. I have found a bunch of good contenders on there. There are also quite a few active forum members in the area so you might get someone to check out something for you if a fly n drive is in the works.
