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.
2015 Ram/Cummins here. Engage TH and EB Lock out 6th gear and let her rip! At 65 mph I'm right in the sweet spot of 1800-2000 rpm. Nothing like it just pulling like a freight train and that diesel humming along!
