It happened about ten years ago in Las Vegas during the 2006 SEMA show. A guy named Doug DeBerti showed up with a F650 and attracted more audience then Angelina Jolie stripping (yes she was hot back then). A 330 HP Caterpillar engine connected to a Alison automatic gearbox provides drive to its 6 wheels that move a cab big enough for 6 people and feature 6 screens. Anything that you derive from the three sixes is up to you, and you did not hear it from us. These monsters won the best in show that year and helping him do this aside from the air ride were the butterfly/Lambo doors combination along with beautifully crafted interior.
