A top official of Daimler-Chrysler says the company might build its new hybrid pickup truck at the plant in Fenton. Either there or in the country of Mexico. Chrysler Vice-President Frank Klegon says a decision will come in a few months. The Dodge Ram 2500 would have an electric motor plus a gasoline engine. But Klegon says the Fenton plant already is running at full capacity, and that could work against putting the hybrid assembly line there.
