For the past four years, General Motors has been trying to sell its medium duty truck business, which produces the giant Chevy Kodiak and GMC Topkick. Navistar, Isuzu and other unnamed suitors were all at one point in discussions with GM to make a deal, but none ever happened and today the automaker announced that it would will "wind down" production of the Kodiak and Topkick and cease production altogether on July 31st.
In addition to the consumer-oriented models from Chevy and GMC, the medium duty truck operations also produced the commercial grade C4500, C5500 and C6500 models. Halfway between a full-ton pickup and an actual semi, these mammoth haulers were best suited for just that: towing. Chances are if you ever saw one on the road, there was a trailer behind it.
The Topkick also earned acclaim for its acting prowess in the Transformers film franchise playing the Autobots' weapons specialist, Ironhide. Unfortunately, success on celluloid didn't transfer to sales on the street, and it looks like Ironhide may be taking his last curtain call in Transformers 2: Revenge of the Fallen.
