Looking for advice and experience. I drive through the mountains every week or two with a 10% grade for miles, mostly without a load but will occasionally tow in the months to come. I have used manual shift to assist braking. I've read in the general forum some find setting cruise going downhill the vehicle will downshift automatically to maintain speed, but these conversations all center around the hemi. I haven't tried that yet, but will.
My question relates to RPMs - when you're manually downshifting to assist braking, how high do you allow the engine to rev, what RPM do you allow your engine to reach before applying brakes rather than downshifting further? Any experience using cruise downhill, with or without a load with the ecodiesel?
