Hello! It sounds like you are interested in a modified version of the StoneCollector mod for FS25. Increasing the capacity up to 120,000 units and removing the speed limit can definitely enhance your gameplay experience, allowing you to collect and transport more stones efficiently.
By adjusting the capacity to such a high value, you'll be able to gather larger amounts of stones before needing to unload, saving you time and reducing the number of trips required. Removing the speed limit will also allow you to move faster across the map, making your stone collecting activities more time-efficient.
These modifications can greatly improve your productivity in the game, enabling you to focus more on other aspects of farming or exploration. Have fun playing with your enhanced StoneCollector mod in FS25!
