I do or my cruise control does on every long 6% grade it meets towing 35k combined. Does nothing to harm it. Engine and trans stay nice and cool.
The Ike averages 7%...and it burns a lot of fuel keeping the hammer down that hard.
From the few times that I have driven it, I would say you are wildly out of the norm pulling that kind of weight without backing off a bit.
The boys from FLT say the Ike is an 8 mile, 7% grade but in reality it is only a 7.8 mile stretch with an average grade of 5.6%. The Ram might have saved 1/3 gal of fuel by slowing down to 1800 rpm on an 8 mile grade but a diesel engine is fairly efficient when it is working hard with your foot to the floor. The worst situation to avoid if you want to save fuel is running high rpm and light load.
You’re down to talking yourself in circles, like every other thread like this.
