I know the standard scene has the hauler with a Peterbilt tractor and I'm wondering if there are any other scenes with different tractors than the pete. Any help is greatly appreciated
I have since gotten max9 with brazil to work. I had a few things installed wrong. I also have gotten a Volvo. I am still looking for others and to learn how to make trailers.
(Sorry, I just realized this post is a couple months old.)
I'm not volunteering, but if you have a lot of time and patience on your hands, you could look into importing and converting some truck mods from ETS2 (Euro Truck Simulator 2). There's an import/export script for Blender called Blender2SCS and Blender can export back out to .obj or other formats. It would be a lot of work, but if you're open to learning and a lot of searching and watching tutorials, you may be able to convert some mod trucks.
The game has European trucks, but there are some US trucks made by modders. The company is also developing a new US truck game, so there is a lot of interest in the community and you may find help there. As always, you should contact the original modders for permission.
