Model 8872 hasn't got that much technic functions but offers a lot of playing options. Therefore I created a three-side pneumatic tipper truck while the overall look is retained to the original. 
The direction for unloading can be chosen by inserting two axles at the appropriate side. A towing coupling is also included on this truck.

Unfortunately, the 8828 Front End Loader is short by the height of one brick to be able to load the truck :-(
