Mod Version 1.55.13.safemode/Mod Version 1.56.2.safemode - September 19th, 2025.

New Features & Content

This update marks the single largest evolution of our Dynamic Freight Market to date. We are thrilled to introduce two brand-new, foundational systems that work in tandem with our existing Dynamic Cargo Rates (DCR) to create the most immersive and responsive economy we've ever built.

Introducing: The Dynamic Supply System (DSS)!

If DCR controls the price of cargo, the new DSS controls its availability. The freight market is no longer a static list of jobs; the supply of goods will now fluctuate realistically based on the season and other economic factors. Expect to see a massive influx of agricultural goods during the Fall harvest and a boom in construction materials in the Spring, while finding those same loads out of season will now be a genuine challenge.

Introducing: Dynamic Economy Parameters (DEP)!

This is the final layer of our simulation, controlling the entire economic climate of the game world. The fundamental rules of the economy—such as overall job availability and global pay rates—will now shift month-to-month based on the market's health. You will feel the world become "Busy," "Sluggish," or "Booming" through tangible gameplay effects, making the monthly Dynamic Freight Market Briefing more critical than ever.

Economy & Market Adjustments

*Comprehensive Rate & Supply Re-balancing:

With the launch of DSS and DEP, numerous cargo rates across all categories have been adjusted for improved realism and balance. These changes, combined with the new dynamic supply system, create a more cohesive and challenging economic experience where both price and availability must be considered for every haul.

Environmental Adjustments

*Day of the Year Update: The in-game date has been advanced to September 20th, 2025, to align with the current time.

Upcoming Changes

*Additional adjustments to individual cargo rates to make them more realistic.
*Revisions to truck/trailer total restoration.
*"Demo" inventory of used trucks from American Iron Exchange, to be used to promote Economy Mod Expansion Pack.

Reworks & Overhauls:

*Ownable Cargo Market Integration & Overhaul:

We have integrated and completely overhauled the content from the "Ownable Cargo Market Rework," a popular but long-abandoned mod by the original author, LAFAYET47. The original mod had not been updated since 2020 and was non-functional with modern game versions. This major update breathes new life into that content, seamlessly incorporating it into the GDC Logistics Economy Mod.

Content & Compatibility: This integration adds over 30 new and unique loads for your player-owned van (Dry Van/Reefer) and open deck (Flatbed) trailers. All original file definitions have been meticulously reworked for full compatibility and stability with game versions 1.55/1.56.

New Cargo Preview: Prepare to haul a much wider variety of freight, including:

Dry Van: Televisions, Clothing, Furniture, Bottled Water, and Pasta.

Reefer: Apples, Grapes, Tomatoes, Frozen Fish, Ice Cream, and Medical Vaccines.

Open Deck: Bricks, Wooden Beams, Straw Bales, and Aircraft Tires.

Agricultural: Barley, Onions, and Almonds.

We want to fully acknowledge the excellent original work done by LAFAYET47 and are proud to carry it forward for the community to enjoy.

Upcoming Changes:

*DCR Support for New Cargos: We will begin implementing full Dynamic Cargo Rates (DCR) support for all newly integrated cargos.
*Economic Balancing: We will be making necessary adaptations to cargo rates and making additional edits to cargo spawning locations to ensure a balanced and realistic freight market.
*Modded Trailer Support (Long-Term): We have a long-term goal to investigate and provide DCR support for popular third-party modded trailers.
