That sounds like a really cool and versatile semi trailer mod for FS25! Having 10 different load configurations ranging from 59,400 to 250,000 gives players plenty of options for transporting different types of cargo in the game. It's great to have the choice of three different styles for the semi trailer - olano1, olano2, and the classic style - to suit different preferences.
The two main ways to empty the trailer - using the floor plus moving mechanism or the classic lifting by the front cylinder method - add a nice touch of realism and variety to the gameplay experience. It's also exciting to hear that there are plans for future updates to add new functionalities to the mod, which will likely enhance the overall gameplay and make the semi trailer even more enjoyable to use.
Overall, it sounds like the OLANO Semi Trailer V1.0 mod offers a lot of customization options and features that will be sure to enhance the trucking experience in FS25. Looking forward to seeing the updates and additional functionalities that will be introduced in future versions of the mod!
