Hi Steammy,
The SCT Truckz Trailerz and Containerz are all available from the DLS, they are all version 2.8 (the oldest version accepted for upload).
I only use TS12 personaly and all assets are error free in TS12, I cannot test earlier versions. (non installed)
If you are using the black page downloads make sure you tick the box TC3 (v2.8).
Below are all the SCT kuids I have uploaded,

40ft SCT Refr Product <kuid2:97008:29047:1>
Static assets
