I'd take that bet. The Ranger isn't manufactured anymore (edit: yes it is; can't recall having seen one though) and I've never seen a Maverick used commercially. I don't think I've even seen one that didn't look freshly washed.
I mean, this isn't even hard to figure out: the F-150 is the best selling vehicle (not truck, but vehicle) in the U.S. for what, a decade or more?
