New to GMC and Sierra SLT. Picked up a 2014 Crew with 6-1/2' bed (standard box). Added a BakFlip Fibermax folding tonneau cover and got the drop in bed-liner insert. So far so good. Still on 1st tank of gas (hoping mileage will improve a bit after the engine breaks in a bit more). I live in a hilly area, so I can't be too unrealistic. Looking forward to some good tips and tricks from the GMC veterans here. Thanks in advance. -ice
