Sunday I will be going down Black mountain. Am I correct that I should: 1. Turn off tow/haul 2. Manually put in 3rd gear 3. Turn on hazard lights 4. Hang on? Thanks
Leave it in tow/haul, auto mode. The truck should downshift to maintain the correct speed. You may have to brake once in a while, but I doubt that it will be much. That's not that long or steep of a grade.
