I get pretty busy with work, selling Lego and life in general but it never really leaves my mind. I wish I had more time to build and usually stick to official sets or popular MOCs when I do because of limited time.
That is a really nice Hauler he has made with a lot to like about it.
Good luck with your reverse engineered attempt - that looks like fun!
I would love to take the best bits from this, the one by Designer Han, and the 42030 B model and make a modernized Technic Super Hauler!
That's exactly what has to be done as instructions don't exist for this one to my knowledge. I have done it and so have many others. It's worth it and looks great especially in yellow!
I built a somewhat modernized version of this model a while back. I substituted new 1x5x11 panels for the partially studded ones and made the gas tanks like the 9397 along with quite a few other tweaks.
They work fine but naturally take a while to move by hand. I just like this tractor for some reason even though it's fairly simple. I haven't built the rear device yet and I'm not sure if I will.
The Container Truck is missing from that catalog - does that mean it won't be making the trip over? I built one already since I had most of the parts and only needed the new pieces but I think it's a shame if true since it is a nice model.
I did this also with the 8275 and the only parts that were super expensive and rare are the pneumatic cylinder brackets (4). I don't remember anything else that was hard to find but I did deviate slightly from the standard set leaning more towards studless wherever possible.
