We live just S/SW of Denver at 8800 ft., and I have only driven up/down from Denver once. Home in Nov, out for this trip in late Dec.
I had driven the 86 in CO for over ten years, and I tend to drive all my vehicles conservatively, so I climb pretty slowly and descend slow as well. I have driven many of the passes in CO, Loveland/Eisenhower tunnel, Vail Pass, Kenosha pass, Monarch Pass etc, most of the time towing a jeep.
The “new” one has an OD transmission, which will help on the downhill.
The key to driving up/down the passes is not to push too hard climbing and start the downhill at a slow speed to minimize your brake usage.
Brake assist on two vehicles is a nice addition in the mountains.
