SnowRunner - 1000L Fuel Capacity V1
Backup Initial..pak (For safety reasons)
Download the zip.
Go to your SnowRunner client Folder (X:\Epic Games\SnowRunner\en_us\preload\paks\client)
Open the initial.pak (you NEED Winrar it didn´t work with other tools at least for me)
Open the zip file and copy the [media] folder into winrar
Start the game and check if the Trucks and fuel Trailers have more fuel.
If for some reason you get no Trucks or invalid Trucks use the backup and start again.
