How to use new truck models, levels or other mods.
I decided to write a tiny how-to for those who cannot figure out how the mods are to be used with Spin Tires.
Unzip the file you downloaded, either from here or elsewhere. Most mod maker place their work in folders which correspond with the folder Spin Tires uses when properly installed. So the content of Trucks goes into Trucks and the content of Sounds (which usually is also present in a truck mod) is copied to Sounds. Really straightforward and easy to do.
Be mindfull to either rename or make a backup of your levelUp.stg file before overwriting it with a custom level.
Hope this helps those that need it.
