  • 2019-11-07 Updated the building instruction: now it has axles dimensions. Sorry, if their absence caused any efforts.
  • 2019-07-11 Updated the building instruction: now it is made in Studio (BrickLink) and the quality is very good! Please re-download it as it has some minor changes and steps optimization.
  • 2019-06-24 Re-uploaded the PDF file with building instructions. It had disappeared somehow and now is available.

Looks ideal teamed with the Mack. I finished it just before the new instructions were available, typical!

The box trailer is a nice addition to the Mack. I really like the modular design.
