I'm planning to make free version in the future but not with the full features of the map and trails. but I'm not sure if it will get to the repository due to it's size file.
You can use a github thing that a beamng modder made to clean up files and take them down from like 1.5gb to like a few hundred mb. Alternatively you can just create a mediafire/google drive link and put it here. What i do for my maps.
