Need feedback from owners of Silverado PU's, 2011 and up.

Friend has a ‘14 sierra 4x4. Crew cab. Its a great truck.
It breaks 20 mpg (cdn) and has had no trouble with it. She bought it new,and is nudging 100,000 km’s.

I have had the pleasure of working on all 3,for ease of repair,tune ups and regular maintenance, gm wins hands down.
Thanks Tooljunkie, good info. Good to hear there maintenance friendly.
