I am starting wonder if some people have towed with a modern gasser or just went straight to diesel. I would say if you over 10,000 lbs and tow more than 5-7 times a year it is time look at Diesel.
I have towed my trailer (2012 32 foot 7800lbs loaded Passpot) with a 2018 2500HD Denali Diesel and yes it has more power, but stability is the same and the difference for the amount I tow is not worth the extra money. I had my last truck 11 years. I will probably have this on for 15.
I have been towing 7500 to 8000lbs for years with two different gas 3/4 tons. Over the Rockies, through the passes in Wa, Idaho, Oregon, California. I use more gas but have not had any problem going 60 over the Contintial Divide fully loaded. The 2017 does much better than than 2002. How fast do you want me to go? It is rare I go over 65 anyway.
Every truck has its place. Right tool fort the job. There are plenty of 1/2 tons doing just fine towing within their limits.
