Strange, I have had standards exclusively over the years, two 2500’s and three 3500 chassis cabs, never had the issue you describe. When clutch replacement time came I would upgrade to a heavy duty double disc which did put more power to the ground and I would notice an improvement. I tend to disagree a lot because I haul about 12,400 lbs. of hay through mountainous terrain quite often to my place, no issues especially with the exhaust brake as an aide. I also haul cattle in a 32’ foot trailer, no issues. The stock clutch I would replace at about 100,000 miles. It weathered my storm well. Also, give me a standard anyday on downhill grades with those loads. To each his own.
