Note from the Author:
I thought the default Peterbilt emblem on the steering wheel of the 579 looked awful,
so I remade it with a better image and in higher resolution.
Before I knew it, I ended up remaking all of the emblems inside and out of both the default Peterbilt 579 and the Kenworth T680,
including all three mudflaps on each.
I even redid the dash brake valves and the logos used in the UI.
