Tow/Haul mode operation
Maybe I'm not using it right, or don't understand it's operation.
I have been experimenting with the transmission a few times out, and when I have the cruise control engaged, BUT I DO NOT have the tow/haul feature activated, I find the transmission WILL STILL downshift at LEAST one gear if the motorhome starts to pick up speed on the down side of a hill. I assume this is because the cruise control is trying to maintain the selected speed, and it cannot apply the brakes, and gravity is causing the motorhome to go faster.
I'm guessing the same thing would happen if you do NOT use cruise control, and without using/riding your brakes, you activate the tow/haul at this time to help slow the motorhome down.
Can someone explain the procedure to use if I'm wrong? In hilly countryside, are you supposed to leave the tow/haul activated all the time? How many gears can/will the tow/haul downshift?
