The release
With the Flatbeds out the day before, the Roadmaster’s lineup was complete: two trucks and twelve trailers across four mods. A player had asked for the family in one download, and TWC Roadmaster Logistics Collection 1.0.0 is that: everything from TWC Roadmaster Tractor Trailer Combo 2.1.0, TWC Roadmaster Deluxe 1.0.0, TWC Quartermaster Tankers 1.0.0 and TWC Quartermaster Flatbeds 1.0.0, the same files as their own pages, in one mod.
One folder
It’s its own mod, not four mods in one zip. One folder, TWC-Roadmaster-Logistics, with one ModInfo, the Roadmaster’s code once, and every truck, trailer and livery kit inside it. It’s built by a tool from the four released zips, each checked against the file the mod sites serve, with the configs the four shared merged in the order the game loads them.
Never both, and a new save
The collection or the single mods, never both: with both, every truck and trailer would be in the game twice and the Roadmaster’s code would load twice. The single mods stay up on their own pages. Switching from the singles to the collection means a new save; moving a save across isn’t supported.
How it all works
The four how-to videos are one video now, nine minutes in game and chapter by chapter, from the Roadmaster hooking up a dry van to the flatbeds packing a base into a conex. Each part keeps its own cards; the Roadmaster’s part, the first how-to, got numbered cards of its own to match the others.
Tested
Taroos tested it on 30 October on V3.3 and newer (the game was V3.4.0). The collection loaded alone, with none of the single mods. In a new world both trucks and all twelve trailers spawned, every trailer coupled, the livery kits went on every model, and Trader Bob sold the fleet. He quit and reloaded the world: the fourteen vehicles came back, and the truck that was hooked up came back coupled. The V2.6 file is the four mods’ V2.6 files, each tested on V2.6 the day it came out, checked against them file by file.
Where
The zip is 310.5 MB, too big to host here, so the downloads page sends it to the two mod sites. Both files are on Nexus Mods and on 7daystodiemods, and the four files there are the released zips byte for byte: Nexus by its own record of each upload, 7daystodiemods by downloading each file and hashing it.
