ATS - Benson End-Dump Trailer (1.39.x)

Update:
Arranged the origins & destinations in accordance with everyone's suggestions.
The resulting job list was a bit short, so aside from coal cargo, there's now gravel & limestone too.
Some issues i couldn't solve.
Only for purchased trailer.
The trailer itself, comes in 3 sizes, and a paintable chassis.
*Required game version is 1.39!
