“…Most videos I have seen (2019) have people flooring the RAM and getting to 45mph on 6% hills towing 28K lbs. What can I expect towing 16k? Does the RAM have enough power to keep up good speed going up hill? If so, what are you towing and what is your tow vehicle?…”
I’m towing about 12,000 lbs. No problem holding 65-70 on some significant hills. Parleys Canyon, I-80 east of Salt Lake and the “Sisters”, I-80 east of Evanston, Wy, come to mind. Along with Scipio Pass and similar on I15 in UT. The Cummins doesn’t care, just more fuel and DEF ;). My 5’er tires are rated at 75 mph.
