I have been tweaking this one for a while, but I believe it's ready for prime time.
Lots of parts, but all are named. Wheels are instanced groups, and the cab is the parent for the whole thing. I left the mirror modifiers in place, and the text as text objects for easier editing. Video shows a WIP - added a few more details after seeing the 360 view (although I could continue tweaking forever).
Update- I did do a little tweaking as I created a rig for this, err, rig. The new, blue model is pending as of this edit.
