The majority of fillable vehicles, including trailers, trains, and seeders, are equipped with this worldwide vehicle specialization.
The maximum fill limit that the user wants the trailer to stop filling at may then be defined. Very helpful if all you want to do is collect a certain amount from a purchasing point or silo.
Each vehicle's limits are kept, and the GUI allows you to reset them anytime you need to.
Enter: – Press R-ALT + L to Open Menu
Important: By design, this patch prevents the maximum capacity from being raised over the default setting.
Only once a supported car has been input and chosen can the menu be accessed.
No input is established for controllers due to a lack of button combinations, however this may be readily set up using the Controls panel.
