The front hydraulic system can be purchased for 1,500 euros in the Miscellaneous store category; it can then be attached and removed at any time using an attachment. Alternatively, the front hydraulics can be purchased with Unimog via configuration; it can then only be removed in the workshop. The separate front hydraulics have the advantage of being easier to attach and detach, but its disadvantage is that it will fall off if you accidentally press the attach button when the front hydraulics were inadvertently selected.

The doors, rear window and sunroof can be opened by dragging the mouse, holding down the mouse button (mouse control).
The Unimog tarpaulin opens with the "N" key, and the trailer tarpaulin opens with the "Y" key.
The configuration allows you to adjust the raindrops so that they are visible on windows during rain, unlike the usual Giants standard, while keeping the wiper area clean.
