In the beginning Toby was sure he wanted an Atlas transfer case, but not sure why. He just thought it would be cool since most of the other cool rigs had one. Then he heard the price and that dream faded. But while he and Todd discussed transfer case options they also devised a plan including the big Cummins, and from there the build grew. Eventually Toby decided the Atlas was the correct option, and he ordered a 3.8 low-range version from Advance Adapters.
