Cummins,

I think I know the place where you are talking of the 14% grade. Is it highway 12 south of Boulder UT? The highway drops down to Calf Creek campground and you reach the bottom of the hill at Escalante River. The highway is marked at 14% so some short stretches must be that steep but if you actually take an elevation reading at Escalante River and another reading 2.5 miles north east of that point the average %grade of the highway over that 2.5 mile stretch is only 5%. Maybe this helps explain how your truck can hold back 33k lbs on a 14% grade.

I am sure that was the road.

Good explanation. Like I said it was wound tight at times. But a 5% grade is nothing for my combo.

I never run auto.
