After reading all the posts about GCWR of over 30K lbs. and everyone drooling over the power of the duramax, I am a bit concerned about the power and or performance of my truck. Without access to a 10,000 lbs load or a dyno, do you guys know of a way I can rest assure I'm getting all the Hp & torque the D/A has to offer? Thanks!

Without a load or a dyno, I would say the dragstrip is going to be the next best way to compare your truck to others. You could also do some 0-60mph timed runs and ask for comparisons.
