Fast forward to when we got the 2015.5 duramax. Gas engines have advanced to the point where towing capability is pretty much equal.
Yes, we still went with diesel, but in reality differences in tow ratings on the gas vs. diesel is pretty minimal, gasser will give higher payload, worse mileage, and need to run much higher RPM on grades. Diesel will cost more, get better mileage, and run lower RPM on grades.
Both will do good job towing in todays trucks. IMHO Pick what you like.
The differences in tow ratings minimal? Not sure what you are referring to, but gasers tend to top out about 15,000# Diesel about 25K to 30K. Payload doesn't mean squat if you can't move it easily at a reasonable speed.
