Reviewed a 2011 GMC SLE Ext. Cab on Nov 13, 2013
Great over all truck and reliable also.. Easy to drive and looks good going down the road. We have taken this on a few road trips and it was very comfortable and fuel economy was over 20 MPG on the freeway.. I also used it to pull a trailer ..I hauled my Jeep and it pulled like a dream..Love the tow haul button with the Alison transmission. I had no issues at all. great Truck for towing heavy loads..

Truck is fine, but fuel mileage is NOT. Window sticker says 21 hwy, but I can't get over 17 mpg driving with a very light foot. Should have leased a Ford Ecoboost and will do that when the lease is up on this GMC.

Reviewed a 2011 GMC SLE Ext. Cab 4WD on Feb 14, 2013
Been extremely happy with truck so far. No repairs or warranty work. Love the room and looks of it. A little hard on gas - but it is a pick up. Been an excellent vehicle in the snow. Should have got power folding mirrors.
