Got $21K for mine...
2WD auto SLT w/65K miles with a minor (not my fault) CarFax.

And the tranny was acting funny on 1-2 shifts...which I've been told is the first sign of "Oh crap" on a diesel Dodge of this vintage.
The '10 F-150 XLT Super Crew 5.4L had $4K rebate and I'm also eligible for the X plan discount.
Driving a new truck for like $9K out of pocket...
