Either its a Freightliner Columbia, or a Coronado. The cheaper and smaller predacessor to the Freightliner Century Class. I have seen all three, yet only have driven the Century Class. The Century is fun to drive, you can turn tighter, carry more weight, (cause its lighter than the Classics, KW'* and Peter Builts)
They are nice trucks, but I would never, EVER drive a purple truck.
