In the 1990s, Seikh Hamad bin Hamdan Al Nahyan of the United Arab Emirates decided to build a giant pickup truck. The result was a truck modeled on the 1950s era Dodge Power Wagon (apparently an iconic vehicle in his country) precisely 64 times larger than the original. It contains a full suite of rooms and can actually drive. The video clip above is from Jeremy Clarkson's BBC documentary series Motorworld.
