Well I wasn’t trying to offend you. Again with your second response I fully agree with everything but your last paragraph. Look I have been an OTR truck driver that ran 80,000 pounds through the mountains everyday for a couple years and climbed 77 from NC into VA at 40 mph every night. I now transport TTs for the Mfgs with a diesel pickup (a weaker one a that) mostly Ohio to West coast so I’ve lived & drive the practical applications of what you speak.
I’ve also raced cars where a horsepower bias was advantageous. I’m not interested in turning this into another HP & TQ debate. I love diesels so I appreciate a torque bias for towing and operate mine as you described for fuel efficiency & longevity. My pickup has 535,000 miles on it. I’ve even driven the old DD 6.2s in the 1500s and there is no denying they were slow and produced as you said low power. To tow the TT as you described compared to today’s diesel pickups with more than twice the HP & TQ seems reasonable to me to describe as requiring patience.
