Pack double trailers for the card “Russian open spaces”
The following models are used in fashion:
– Non-tarpaulin semi-trailer and nefaz tank semi-trailer with permission of the author. Author: “Koral”.
– Short timber trailer. Authors: Syncron3DCreations, Patrick Poulsen, MDModding.
-Trailers in orders are only in Russia, Poland, Germany and Scandinavia. Added the ferry Novaya Ladoga-Gdansk on which you can get to Europe.
The mod works without a map “Russian open spaces”, but there will be few orders.
