Here is my finished Peterbilt 379 lowboy. The truck it remote controlled, the trailer has a detachable neck, and the wheel loader has full power functions. The wheel loader could also be set up for RC. This MOC took about 3 wheeks to complete, (mainly because I was waiting for bricklink orders to arrive). It is the largest technic creation I have ever constructed. The wheel loader uses two linear actuators to control the bucket. the exhaust pipe is also the function selector. The wheel loader can also be steered with the steering wheel in the cab. The steering uses two 9m links attached to a transverse steering arm that is connected to a 36 tooth gear turned by a 12 tooth gear. This setup is incredibly smooth, and is very simple. It also somewhat repilicates the steering on an actual wheel loader.
