In fact, it is important to look at local policies and regulations. If the management of the vehicle management office is relatively loose, then you can choose 6*4. If it is strict, then only 8*4 chassis can be used.
Compared with 8*4, 6*4 is cheaper, but the angle between the fuel tank and the ground will be smaller after 8*4 modification, that is to say, the height of the whole vehicle is smaller, the overall layout of the vehicle is more reasonable, the stability and rollover resistance of the vehicle are stronger, and the service life of the vehicle will be increased accordingly because of the reasonable overall layout.
