Get used to it man....It's part of the XOC. If you can't hang with the Big Boys, leave.

At this point, don't expect to get ANYTHING above and beyond what those sites say. Your truck is old and outdated. In all honesty, I'd be surprised if you get what's listed on those sites. It doesn't matter if it's got 27k or 270k miles on it. If someone wants it bad enough, they'll find a better deal than what you would offer, guaranteed.
