I have a 14 sport. I absolutely love this trim. Im coming from 2 express trucks (a 14 and a 16). I feel that this trim is top notch. i probably could pick it apart and find things that are not perfect, but for a 2014 its got a ton in it. Im happy with the leather quality, Heated / cooled seats, heated steering wheel (best thing ever), sun/moon roof (it doesnt leak), power fold mirrors, active grille shutters, better lights (not led, but much much better than express quad lights), etc. And i love the look of the sport. the grill and front with the hood go just perfect together. I highly recommend getting the 392 gears. I had it in my 16 and it was much better. Do not worry about gas mileage. its a moot point. or just get a v6. As far as the 44-44 in the sport goes, i was just made aware of a switch that can be installed to lock up the rear. I know nothing about it as i just received info about it. Ill see if i can upload the link for the youtube video. Im told its a $160 part (shipped) and 15-20 minute install.
