Kalmar Ottawa Commando
The yard spotter that put Ottawa on every loading dock in America.
The Commando series (Commando 30, Commando 50 and CYT30) was the volume-selling Ottawa generation that preceded the T2; built in Ottawa, Kansas through about 2014, huge numbers are still shuttling trailers in yards and intermodal terminals today, making it one of the most-serviced legacy nameplates in the parts aftermarket.
