Viss Valdyr's Physics Mod 1.30
This Mod is my try on doing a physic mod. It may be a bit rough on the edges, but with your feedback, it can get only better. It is also fully compatible with my "Everything unlocked" mod and should have a higher priority than Eu.
It tries to emulate the movement in the cabin a bit better and makes the truck a bit more "heavier" in regards of driving.
