stonysmith@DanPizz There is no currently manufactured chassis that would fit this. At best, you'd have to buy an MTL or AZL chassis and chop it up to fit. Another possible choice would be the Rokuhan Shorty. The Shorty chassis is mostly plastic and would be easier to modify.
The container can transport most any material - grain, cement, etc.
I added a picture above that I used as my source.

As of May 2018, none of these (Nscale) have yet been ordered. However, the one in Zscale (37% smaller) has been printed 15 times and works wel. As with most of my models, it's fully articulated (even the seats move) and there is a pulley on the main axle such that you could rig up a motor to spin it.
