My actual experience with GMC:
2009 2500 HD, 6.0L gas - 6-7 mpg towing and about 12 mpg not towing.
2013 2500 HD, 6.7L diesel - 11.4 mpg towing and 17 mpg not towing.
2018 3500 HD, dually, 6.7L diesel - 12.6 mpg towing and 18.2 mpg not towing.
The 2009 numbers are my best guesses from memory. The 2013 and 2018 numbers are actual hand calculated average mileages with 194 tanks of fuel in the 2013 and 38 tanks of fuel in the 2018.
Did you mean 6.6 liter diesel?
