Welcome to the forums. It would help if you added which Cummins engine but it's probably the 6.7L ISB engine. Great little engine but at only 800 ft/lbs of torque in that heavy a coach you will notice adding 1500+ more lbs. On some of the high/long passes in CO I'd probably let someone drive a Tahoe up and over. This will make it easier on the ISB and your brakes as they can gear the Tahoe down too on the way down.
