Ok, I finally got my ass up and going and compiled a speedbuild video. The Mercedes-Benz Arocs is a fantastic example for a proper first try.
I can say, the build was very enjoyable. Lots of interesting techniques and a lot of firsts for LEGO Technic, like a truck with suspension. Apart from that, the Arocs is not only the biggest set ever in terms of parts, but also it has the most wheels as well as new and updated (!) pneumatic pieces, mainly longer cylinders and better inlet ports.
Buildtime: ~6 hours
I hope you like it. If you have suggestions or feedback for me, please use the comments section here or below the video.
