While the most complicated Lego we've ever assembled, the instructions were the best and the assembly went well. It took my 17-year old son about 20 hours to assemble.

We put it together and this is the funnest way to get snacks from the kitchen! LolThis set is massive but not difficult to assemble, but it is large and barely fits on its shelf. Totally worth it!

Great gift
Christmas gift for my son. He was absolutely thrilled with it. And the D-11 Dozer is huge!

A family of fun!!!Don't be in a rush to construct the set as fast as possible. One missing piece early on could result in having to take it apart to install the missing piece. I speak from experience on the Volvo Articulated Hauler.Go LEGO!!!
