Did a quick look on the Chevy site and the 2014s have improved the brakes on the 1500s with 4 wheel discs all the way around. With the 6.2 engine, best in class power, 3.73 gears and bigger rear axle, NHT package and 21 miles per gallon with 420 HP.....hmmm:

Don't understand the difference in price either between the extended cab and the crew. Looks to be closer to $4,000. My dealer says everyone wants the crew cabs by a wide margin. Resale alone might be reason enough to go with the crew?
