Dwarfed is an understatement. I've seen a few and must say these are just plain redneck cool!
The concept is simple. take an International medium duty 2x4 or 4x4 truck chassis, 2 door or 4 door cab, trick it out with all the chrome goodies like stacks, wheels, bumpers, grill etc... and bolt on a ford F350 dually pickup bed.
The rear wheels/tires stick out past the sides of the ford pickup bed dually wheelhouses by several inches.
With a 570 cid International under the hood, there's up to 1300 ft*lb and 340 HP available. They've been selling faster than they can be built.
