Just so you know (unless they have changed it recently), every mod except the Cow Simulator on the Steam Workshop will not download into the correct location.
Figuring out what we can do with the Main Campaign and how to do it has involved a lot of trial and error, mostly due in part with the lack of official word on how to do so. LarSeb said he would be making a tutorial/guide on this subject today, so I am looking forward to that.
