Stock Torque curve graph?

Stock 6.9 torque curve graph? Can't find one. Would like to look at one to get my gearing right for the way I will use my truck.

Thank you for that, interesting article. I was worried about cruising rpm getting to low, around 17-1800 @55mph, but I guess I really don't need to worry. My rig weighs around 7500# and won't be going up much when I do the minimalistic buildout.[Camper] Will never be towing with it, just putzing around except when in traffic.
