Good time of day. I present templates for DLC Tirsan trailers from SCS. All templates are in the Tirsan DLC folder. There is also a registration for Mods Studio 2.
Open the User Vehicles folder and move all files to Documents/mods Studio 2/User Vehicles.
There is also a Tirsan folder. This folder contains previews for Mods Studio 2. Open the folder with the Mods Studio 2 program and follow the path Mods Studio 2\v.xxx Data\ModData\SCS\Vehicles\Images\Tirsan\ETS2 and copy the Tirsan folder here.
