I know some may think it's my imagination, but the computer does adjust to the way you drive. Just sayin'. Again, I said this with the disclaimer that I had not towed in such incline/decline as many of you, so this symptom you all are describing is news to me.

Anyway, I have yet to ever have to hit the brakes that hard while towing the camper, to experience what you guys have described. Like I said, I had to romp on them once at about 45 mph for a vehicle that pulled out in front of me, and at about 40mph, the truck grabbed second and slowed us down. But that was it.

Either way, sounds like the truck is doing what it is supposed to. I will leave mine in auto and let the computer do the work. Having to shift it manually, especially in a twisty decline, is not my cup of tea. When there is 9k behind me, I prefer 2 hands on the wheel.
