Even without tow or engine braking, I found CC on freeway downgrades annoying.
When I pull my cargo trailer I set CC to 65 for fuel saving, but I don't mind to speed up for free on nice long grade on desert even to 80 mph.
Than at 67mph the CC downshift and slows me down.:M
Aye, there's the rub.
With CC set and TowHaul on, it gives the truck permission to hold to whatever speed it was set to.
If it's set to 55 mph going up hill, it will hold at 55 mph.
When it crests the hill and starts downward, it will downshift and hold speed to 55 mph.
It's not a good thing if you prefer to free-wheel on the downhill side.
