The gargantuan Ford F-650 was a favorite among hulking NFL players and lottery winners with piles of excess cash to burn.

Powered by the reliable Cummins diesel, the custom SUV conversion on this fly yellow F-650 was done by Alton Truck in Michigan in 2005. Along with a host of cool upgrades, the truck features a custom Kelderman air ride suspension and custom conversion leather seats.

It recently sold at Barrett-Jackson's Palm Beach Auction for a cool $50,000.
