By default, the ETS2 mod folder is: Documents/Euro Truck Simulator 2/mod/ If it does not exist, create it manually.
It seems you are looking for a detailed guide or essay-style explanation regarding the download of a “Mod Truck Mercy” for Euro Truck Simulator 2 (ETS2), specifically for game versions 1.41 to 1.4x. However, based on available modding databases and community resources (such as SCS Software forums, ModLand, ETS2.lt, and ModHub), there is no widely known or officially uploaded mod named exactly “Mercy” for these versions. It is possible this is a misspelling, a very niche or private mod, or a name used in a specific foreign modding community.
Place the .scs file (or extracted folder) into mod/ . Do not rename the file unless instructed, as mods often rely on internal path names.
