There have been some phenomenal functioning replicas of semi's before, but this mini Kenworth takes the cake. The RC masterpiece took 2850 hours to construct and features a 5 speed Cummins engine. This replica doesn't just look the part, it actually is a fully functioning replica that can do everything a full size Kenworth does. The "model" isn't cheap though, it's about half the size at twice the cost.
