When towing with my ram diesel how do I tell when I should downshift. it seems to tow so easy, but slows when going uphill at 60 what should my rpm show.
Just came back from a trip Flat ground stayed mostly around 1600 Only on climbs did I see it get to 2100, and I tried not to hold it there, but I guess I could. TH mode would keep the rpms up higher.
