ATS Expansion will not be as ambitious as the original for obvious reasons.
THERE ARE 3 REQUIRED FILES, THE MAP AND DEF FILES ARE DOWNLOADED TOGETHER, THE MODELS/ASSETS ARE A SEPERATE DOWNLOAD, THIS BEING DONE TO MAKE IT EASIER FOR THOSE WITH A LITTLE SLOWER INTERNET.
Link for the models and assets found here on trucky.
Thanks to Googles56 for ATS Expansion truck skins,
Thanks to Sineptorro for Big Bud and Magnum models, and adding them as cargoes,
Thanks to Darkness for the use of his models,
Thanks to beta testers Kaiser and Marian @GMC Logistics, and JohnSeeger
