Kenworth W900 Rear Steer 8×6 v1.0 ATS
Made by request to change the default config to a rear steer drive axle on the SCS KW W900 8×6 chassis; this should work with any game version after the addition of the 8×6 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.
