I started a thread like this a while ago over on DTR. Basically seems like the cab-over design is dangerous for the driver and yields poor fuel economy because of aerodynamics. Not to mention, the pita and danger of working on the engine that's sitting underneath a cab. Hence, it has been unpopular here in the states. The ONLY benefit of a cab-over design is that it is more manueverable in the [censored] tight streets of Europe.
