If you are looking for absurdly over the top pickups, Hennessey Motor's Velociraptor 6x6 probably takes first prize at "only" a little under $499K. They start with a Ford F-150 Raptor and then mode the daylights out of it. I suppose it's not surprising the company is located in Texas, Sealy, TX to be precise - that's about 60 miles west of Houston on I-10. And if a pickup isn't to your liking, they make a number of other extreme vehicles.
