2022 Ram 1500 2wd. Got 20 mpg on first long trip with very low mileage on odometer. Now at 14K miles its developed a vibration when feathering the throttle out of ECO/MDS and the gas mileage has gone down noticeably. Was 15 city 20 freeway, now 12 city 15-16 freeway Hemi 5.7 / 3:21 gearing Any answers to issue would be appreciated

Here in Wisco it's COLD! I'm finding that ECO/MDS on the freeway is fine (and mileage goes up if easy on the throttle), but around town and on slower roads, my mileage is better in Tow/Haul Mode and will slowly creep up, whereas it'll creep down in ECO/MDS if lugging around 12-1300rpm. My G/T has 3.92 Anti-Slip.
