This is LEGOŽ model 5865 MiniDumper, part of the 2009 Creator series. I thought it looked really cool and was curious how close I could get to the original by building a virtual one.
Fingers crossed that I come close with just the inventory list. It gave me an excuse to model some new bricks as well as fix a few old ones. And yes, the back can dump. I just didnt bother for this image.
