It looks very esthetic and cool. The only thing is that the steering needs the white colored cog wheel with soft rubber center, because I heared the inner parts cracking because of the leeway, when the outer level of steerign has reached. If you a little redesign the sttering part of your truck by applying a cog wheel with soft center, that problem will maybe solved. On the Ferrari 599 GTB four seater that i'm working on, I also applied it and now my steering compartiment doesn't show any leeway and I don't hear even a small crack. It works on my model.
Well done Joel
It is nice to see someone not only building nice working models in Technic but also developing them further.
Version 3 - would it be possible to hide the steering motor a bit more?
A truly great model from a 13 year old!
