Kenworth W900 Rear Steer 8x6

Made by request to change the default config to a rear steer drive axle on the SCS KW W900 8x6 chassis; this should work with any game version after the addition of the 8x6 option but has not been tested on older versions.

This can be turned on and off by activating or deactivating the mod through mod manager; you do not need to buy/sell the truck any time you want to change it.
