What this mod does

Side dumper trains is a mod by Tommygun that turns SCS’s side dumper into multi-trailer trains. It’s under 300 KB because it only adds configurations, with no new models.

Configurations

  • B-trains of 3 to 6 trailers.
  • AB and BA triples.
  • BAB, ABB and BBA quads.
  • BBAB and BABB quints.

You can customize the wheels, paint and accessories of each configuration.

How the cargo works

They all carry dump cargo, which you can take from the freight market or from the TruckersMP dispatcher. There are no state or company restrictions, although the author recommends large companies for the longest trains. To avoid absurd loads, the cargo weight is capped at that of a normal trailer.

Multiplayer

According to the author, it works in single-player, Convoy and TruckersMP without being enabled; you only need to enable it to buy the trailers at the dealer. In August, a user wrote that it didn’t work for them in Convoy, with no reply. It was released on May 31, 2026 (ATS 1.59 era). If you like long road trains, also check out B-Double/Triple SCS Box Trailers.
