Truck Mods (Engine Sounds Only).

[USA Trucker]

... and this is why I ask all Mod creators to post instructions, and include which version they are modeling. This is especially true for Steam purchasers were if you change some portions of the game the Steam DRM won’t allow the game to work, or work correctly. My advice is to make sure you back up your original files first before using any Mod. If you don’t do this, your use of the Mod is at your own risk. Modelers assume no responsibility for their usage.

I don’t think the version number matters unless it changes the sound files significantly, but the language version may be quite different. Being that this is the English forum I can only assume that all Mods are created for this version.
