I've got a 2022 Ram 2500HD with a 6.4 Hemi , 6.4 bed and 6-speed tranny. Mileage is 13,700. Does anyone have experience or insight for using the tow/haul mode when driving in a city with slow speed limits to avoid the downgrade to ECO mode? I'm not liking the ECO shuttering and low RPM's until it shifts back to all 8. TIA
