I have a 2021 Silverado Custom 1500 with the 2.7L turbo 4 cylinder with 8 speed transmission. I don't tow anything, but put a lot a miles on. Got it a little over year ago and hit 41k miles this week. Pretty no frills truck. That little motor has been great, plenty of power for commuting off and on road. I'm getting just shy of 21 mpg on 10 ply all terrains tires.
