What this mod does

GMC Community – Official Traffic Pack puts trucks and trailers with the GMC community’s liveries (formerly GMC Logistics) into American Truck Simulator traffic. The liveries are by MarianGMC and Stonerish420 and are applied to SCS vehicles, so it doesn’t add new models.

Trucks in traffic

  • International Lonestar 6×4, 9900i (day cab and sleeper) and LT (day cab and Skyrise).
  • Kenworth T680 6×4 and W900 6×4.
  • Mack Anthem 6×2, Freightliner Cascadia 6×2 and Peterbilt 389 day cab.

Trailers and other vehicles

  • SCS trailers: 53 ft dry van, chip van, dump trailers, doubles and triples, Rocky Mountain, curtainside, food-grade and fuel tankers, bulkfeed and side dump.
  • AI vehicles: Dodge Ram 250, Ford Transit (two versions), Ford F-150, the Tourliner bus and the Tempsa Opalin.

Version

Version 7.2, released October 19, 2026, is for ATS 1.61; September’s 7.1 was already for 1.61. The pack has been around since June 2024 and has been updated with every game version.

The page doesn’t list requirements, DLC or load order. There’s a sister version for ETS2 with its own mod page on Holymod.
