Klaas Economy Mod v1.1.0
I recommend creating a new profile, this mod can be used with existing profiles but you it will not work properly.
This mod offers a realistic economy, inspired from real-life trucker wages. (minimum wage is ~0.5€/km for Quickjobs)
Bank loan limit increases at each level. You will be able to buy a truck starting with level 8.
You will find more informations on Steam Workshop.
