I recently purchased a used 2019 Ram Bighorn 1500 4x4 with the 5.7 Hemi. Gas mileage sucks. I previously had a 2014 and got around 16mpg in town and around 22mpg on the highway, not towing anything. I’m getting around 11.5-12mpg in town with the 2019. Is there anything I can do to help get better gas mileage?
