The International site says a CDL is not required, but some states may impose restrictions on operating the vehicle.
The Detroit News has an article on this truck (
http://www.detnews.com/2004/autosinsider/0409/14/autos-271524.htm), which pretty clearly is aimed at the "Look at me" set. A few are on the street, but they don't expect a large production run.
One problem is its size. It's two feet taller than a Hummer H2, and
four-and-a-half feet longer. It clearly won't fit into a standard garage. Since the price is north of $100K, many finanically-capable buyers live in developments that prohibit outside parking (or at least parking trucks outside).
