Good point John. And I've done a comparison between a 2003 SO Cummins Ram and an identical 2005 Hemi powered 2500HD. If I were deaf and didn't have a tachometer, I wouldn't know the difference towing our 10,400 lb Jayco 5th wheel. The Hemi would actually tow it faster up the grades although it was at 5k rpm/70mph. I usually set cruise at 65 in the interstates and 60 on the back roads and let it shift and do it's thing. The Hemi from direct to second and the Cummins from O/D to direct on the uphills. One shifted as much as the other. Never hurt a thing. Cringe factor is not an engine weakness or transmission problem. More of a mental problem.:B
