Lego old truck MK2

This has been a steady build over the past six months - I've picked it up looked at it then put it back in the draw again more times then I've actually added to its progress. I've been wanting to rebuild the the old version for sometime because I really enjoyed the process, making something in this way is far easier than finding a real life version to copy.

The new version is more detailed than the old, which means it has more weight. The chassis is pretty much unchanged apart from swapping the medium drive motor for a more powerful large motor

The model when attached to the trailer is quite long but has a very small turning circle. This is achieved by linking the tow bar to a rack and pinion steering system which connects both trailer axles together - each axle steers to its opposite, which reduces the turning circle by a huge amount.
