    After recently building jb70's RC MOC of the Mack Anthem I have been working my way through building some of the different trailer MOC's on ReBrickable. The Mack low boy is a really nice MOC with good design and functionality. I actually like it a lot more that the Arocs SLT low boy, also from CB, that I built several months ago. At this scale it works much better in terms of overall weight when driving or turning. I also think the manual dolly is preferable to the RC version on the Arocs. All said though they are two very nice MOC's, but this one is more playable. As usual CB has produced very nice instructions and I believe the cost is justified. Only minor change would be to specify how long the studded beams are in each step, I made the mistake several times using the wrong one and had to go back a few steps. I've uploaded several photos with many of the details shown. Now to find some cargo to transport at Mack scale...

      Added photos of my own MOD of the lowboy trailer for directly attaching to a tri-drive version of the Mack Anthem. The tri-drive MOD is by VoidSerpent. The Mack is the Sbrick MOD by jb70. I've included some zoom photos for anyone who wants to replicate this simple MOD. Instead of needing the dolly, the weight of the cargo bed and load is directly over the tri-axles. In this configuration it's much easier to drive, especially reversing. There is a lot of Mack MOD's and trailers that have been designed, I've had fun making my own MOD of these.

    这个拖板很好 但是无法载重别的东西 底盘会直接接触到地面的 有办法改进吗?

    Bought the moc and made it and it's looking great behind my Mack.
    The only problem is, it can't transport almost nothing without reaching the ground. Its bending down at the point the arm begins ( just behind the rotation ) with results the deck reaches the ground. With a brick below the arm and dolly it can carry my 8043 with little bending.
    Maybe some1 have a better idea?

    imho, 20,-€ just for building instructions is just way over the top . I won't claim, that this is a rip-off, but the model we see here DOES look pretty similar to motomatt's free lowbow trailer (MOC-4846).

      But there are many differences such as this one is pure technic and moto matts is technic beams and plates
      • 1 year, 3 months ago HangmansJoke Level 8 MOC Designer
        absolutely true, I have to admit that.
        PLUS (and that is a huge big plus) This one is an alternative model for the 42078 - Mack Anthem (what a great set)
        Since the inventory states that it has 1201 of the original 2590 bricks used that is not really a high percentage of parts used, but it is good to know that I can put this together, when I get the Mack twice.

        My primary point is: 20,-€ does simply go against the basic idea of 'by the community - for the community'.
        IMHO asking for a little amount as a sign of appreciation is OK, 20% of the whole LEGO set is just too much.

    Really good to transport some Vehicles with the trailer.

    Very nice MOC.
    I am willing to believe your work is 100% original, but I would like to suggest a few things to improve the credibility of your claim:
    - refrain from insulting people ("lie", "stupid") who are merely pointing out the obvious (it is a fact that it looks very similar to MOC-4846)
    - post an image of the original model so we can better understand why the 2 MOCs look so similar
    - acknowledge the existence of MOC-4846, the similarities with your work and point out the differences / improvements if any
    - acknowledge inspiration from it if your work was indeed inspired by it (credit where credit is due), there is nothing wrong with drawing inspiration from existing models and improving upon them
