Heavy-Haul Trailers Adjustments updated for American Truck Simulator game version 1.50 archive packed for the new HashFS format. This means instead of the zip extension the archive file now uses the scs extension.

version 2.2 changes:

  • archive with HashFS format using new scs_packer
  • removed duplicate cargo definition

Update by delete old and replace with DTHHTrailerDef.scs in your folder, /American Truck Simulator/mod/.

Download link and details found on Heavy-Haul Trailers Adjustments page.

Game version 1.50 brings an updated California map, so I posted an improved heavy-haul routes map for latest roads, length-limits, rest places, and cities.

Update 21 May: maps updated for Nebraska and corrections for Oklahoma
