I sold a 1997 crew cab xlt 4x4 auto 120k, almost perfect condition. Pulled a 34' airstream less than 10k miles, other than that all empty miles. One owner, that was meticulously maintained. for 13,750.00 in late 2007, or early 2008. The truck had an original sticker price of 37k, was bought new for 30k, and sold 10 years later for almost 50% of original purchase price. I was pleased, and the buyer was pleased.
Here is a pic of the truck I sold.
Here we are four years later, and I think 11k might be on the high side, but if it's what you want, what's the difference in a couple grand in the big picture.
A little different scenario, but something to chew on.
I just purchased a 1999 Dodge 4x4 dually, loaded with Ranch Hand front and rear bumpers, steps, spray liner for $6100.00, the seller was asking 9800.00... Maybe you can offer 8-9k on the truck you are looking at, and see if they bite.
