Rigid Chassis Addon by Kast v1.0 – 1.47
This is completely new mod, keep in mind that older rigid addons plus other addons wont work with new mod. Before updating, i recommend change chassis to regular semis (to keep the odo kms) or sell trucks.
With new mod, there is BASE mod and truck addons. Just download base mod and addons for truck you like to have new chassis.
