Attention! They are now a real rear-drive semitrailer tractor, not official all-wheel drive. Don't drive on rough surfaces. Saddle height of this tractor is low, So most of the higher chassis semi-trailers may not be suitable for coupling with it. This mod contain 2 tractor at present. I may add more chassis configuration in the future if I have time.
