"Our dealers did an outstanding job in 2019, not only with meeting consumer demand, but also handling the introduction of the redesigned Ram Heavy Duty and new Jeep Gladiator," Reid Bigland, FCA's head of U.S. sales, said in a news release. "We have read the expectations that sales may slow a bit in 2020. However, we believe there is still plenty of demand in the market and we are ready for a new year."
