Building Mod
The packaging and uploading process for the truck mod is identical to the general processes described in the Build & Upload Mods article. The main difference is in the content you include in the package.
In the Assets section, click Add Asset and specify the mod files:

Add the following resources that are relevant to your truck:
auto_*_truck_info.sso.resourceauto_*_truck_wheel_info.sso.resourceauto_*replicated.sso.resourceauto_preview_*_truck_wheel_info.sso.resourceauto_preview_*_truck_preview_info.sso.resource
Where * is the name of your truck, such as tuz_119lynx_mod.
