The 2024 gets 12mpg around town even with the 10-speed trans. Never gotten better than 17 on the highway. Really disappointed in what GM is putting out nowadays.

Yikes! That sucks for mileage. No wonder you are not happy. I got 25 mph on the way home from buying it from you in Chicago but have only managed a best of 19.6 on the highway since though it only drops to about 17 mpg in town. My crew cab diesel will pull 24 freeway and 17 in town. Love all 3 of my trucks for each of their intended purposes. I was going to sell one when I bought yours but it's been so good I decided to keep it.
