I have never had to have my truck hit 3000 rpm to hold my speed and I am well over my GCVWR. There's no need in it . Besides, I don't know if the 2002 5.9 in the OP will turn 4500 rpm.

He pulls a grade 200 rpm below peak torque. Can you do that? Maybe 200rpm below peak horsepower at 1200 rpm above peak torque. I cruise on the interstate nearly 2000 rpm below peak torque. Why do you need to run 400 rpm above peak torque? Why do you need to run 2/3 of your rated rpm just to run empty? Can't tow your rated capacity at 1400rpm like real trucks? Nope. Yours has to scream at 2000-2900rpm well above peak torque and often nudging the governor. Putting it into perspective I'd say yours is the one struggling. :B

I'm not going to do this with you in this thread. There's already a thread for that. You and Dodge guy are trying to turn this into a gas verses diesel thing and that's not what it is. The OP wanted to know if his speed and RPM were about right for his engine. Someone says something about thinking it was slow for the weight the OP posted and makes a comment about in his opinion there should be a minimum speed a truck should be able to tow its load and you guys automatically take offence because the OP has a gas motor. If it were a diesel with the same power you would have never said a thing.
