Item description:

All trucks are unlocked (except Scout 800).
Only 2% of the game completed (immediately after the tutorial).

Tested on game version 32.1, the official STEAM version. (no DLC)

Installation:
Steam - go to the game folder, follow the path where your saves are located (for the steam version it will be: "C:\Steam\userdata\"your number"\1465360\remote") make a backup copy of CompleteSave.cfg and paste the downloaded file with replacement.
EpicGames - rename CompleteSave.cfg to CompleteSave.dat, insert the downloaded file with a replacement where your saves are located.

Important: you need to install it over the existing save, when the first garage is already open, after completing the tutorial (you can disable it in the game settings, then the garage will open immediately)
