This is a rather Low Poly 3D Model of a Mining Truck 789D. Those are sometimes also named Dump Truck.
It is already set up to drive around with Wheel Colliders in a physical manner.
There is also an Animation involved to open the Cargo Area. It is pre-animated because the Hydraulics are usually not easy solved by code.
