Does anyone know how to add these trucks? (Spintires)

1 downloading archive
2 in the archive folder there is steam_mod put it in the folder with the game
3 in the archive from the user folder pull out the Config.xml file, and drop it with a replacement in the game pack / in the user folder
4 if after that these units did not appear in the game then delete the game cache and store everything.
C: Users your computer, or rather its name, for example, I have lenovo AppData Roaming SpinTires,

I have all these mods work without these problems, if you have a licensed game, then you can install all the mods from the Steam workshop.
