I have a 22 crew cab LTZ with the 3.0. I love it, smooth power band all the way up and down. I don’t drive quite like you, some interstate but mostly two lane highways and in town driving but I get 30 plus and on longer trips upwards of 32 mpg. I did a little bit of towing of trailer weighing about 8000 lbs. and also got about 20 mpg. I have just under 7000 miles on it so far. This is also my first experience with a diesel but like my dealer told me when I ordered it I would be happy with it and I am extremely happy with it. So glad I didn’t go with my original choice of the 6.2 now with the fuel prices. For 20% more per gallon for diesel I am getting 50% better mpg. Thats if I didn’t burn premium like they recommend for the 6.2, that is equal or exceeding the price of diesel. I hear people say “well you have to buy DEF” well so far I haven’t added to it yet and gauge is on 3/8ths. Not a big deal at all.
