Sorry for the criticism, but the truck is badly made. The Renault Premium trucks are short (only 35 cm. more than the 4x2). This is achieved by changing four pieces of place. Add a second axis, not make it a 6x2 or 6x4. Also, hide the second axis in the 6x2, to hide the differential assembly, a bad trick. If a steering shaft, differential assembly has not. I suggest viewing photos and videos of this truck. It is a beautiful truck, but no modeler, succeeds in doing so correctly.
