I agree with the $5000-$6000 pricing. I've seen lots of comparable trucks out there in that price range...particularly given the economics going on right now.
As well, I agree with dubds about the Longhorn comment. They are rare...but that doesn't mean they are necessarily desireable.
A lot of owners say they won't sell it unless they get their price....most of that is blustering. Be respectful and simply state that you are very interested and what your budget is....and make sure you leave your contact info with her. Then I would respectfully follow up....after Christmas. It's important that the you let the seller maintain a sense of success in this, even if that means the sell price is lower than what they originally wanted.
Good Luck
