As far as I can remember, it was Trevor's Peterbilt 359 pulling that yellow triaxle lowboy with the Agora bus on it.
Between the garage and the airport, on Aspen Grove.
The heaviest cargo at that time was a 50T heatexchanger, I just tried and tried lifting it with the default Liebherr crane...
I saw this video () and downloaded this game when I found out it was free. That was around 2006 or 2007.
I played it for some years, even began modding some basic N/B trucks (Trevor's Peterbilt 359 for example).
Took a pause and came back to it 2 years ago.
Love this game.
