I have now the same problem in ATS as in ETS2.
due problems with pastebin I send log to Oleg by mail.
I understand you are very busy with the updates but my advise take a look at the trucks in combination with owned trailers.
in ETS2 I drive now an SCS Volvo the same mods and errors or crashes.
when buying the truck did not change interior.
