So I bought my 19 with the 2.7T LT 2WD this last October. I now have 17k miles. I average 19-20 mpg with my daily driving and Uber.
I have taken road trips with just passenger payload and luggage and can get 22-24 depending on where I keep my speed.
Not long ago, I hauled an 03 CTS on a Uhaul auto transport on the interstate. I still averaged 13-14 mpg going 60-70 mph. Plenty of torque to get the trailer moving and keep it going on the highway. Plenty of power to pass on the highway as well.
I thought I had made a mistake going with the turno4, but now that I have put 17k miles on it, I couldn’t be happier. Sometimes I wish I did get the V8, but I remember the reasoning for buying the turbo4.
Coming off a 2003 Ram 1500 4.7, this Silverado already outdoes my old truck. So it meets my needs. I don’t haul all the time nor do I off-road.
