1980 Kenworth K100 cabover truck custom red interior at the show in Wildwood Florida

The 1980 Kenworth K100 cabover (Cabover Engine, or COE) remains one of the most iconic, highly sought-after classic heavy-duty semi-trucks in American trucking history. Introduced originally in 1961 to maximize trailer length within strict state regulations, the 1980 model represents the pinnacle of Kenworth’s traditional mechanical era before advanced electronic systems took over.
