I know a lil late... but......Well I got my 2014 Silverado 4.3 v6 standard cab...in 2015. Solid Truck! only 3 things that get to me sometimes about it.... 1st 13MPG city 18-20 hwy. 18 at 70 and 55mph I get 20 ..2nd Idles rough period after 1st week owning it... 3rd AC has mind of its own sometimes .. wont turn on for 1-5 min after starting, sometimes or just turns off.. says it on??? Nothing blowing no compressor kicking on either so? Told from dealership even after 1st oil change 5k I needed injec- cleaned.. a NEW truck needs a service like that?? wth! They just idle like that!... ac can't find the problem. for power an mpg.. guess I should have spent 5k more for the 5.3? and got a back seat/4 door... anyone ever get better mpg ????? Out of town with a rented 2018 5.3 umm 17 city O.o???? not sure highway yet........
