Full Description: Clean Car Fax on this 2017 GMC Sierra 1500 Crew Cab Short Box Denali! Loaded with all the goodies! The 2017 GMC Sierra 1500 is available in four trim levels: base, SLE, SLT and Denali. They are available in various cab and bed configurations.rnThe base is available only with a regular or a double cab and is sparsely equipped, though options are available. We recommend buyers look to the SLE trim level at a minimum because it has features beyond just what you'd find in a work-only truck. The version that strikes the best balance between amenities and functionality is the SLT trim level, while the range-topping Denali's luxury will appeal to buyers who want it all.rnConfigurations are as follows: Regular cabs are offered with a 6.5- or an 8-foot bed, double cabs come only with a 6.5-foot bed, and crew cabs are available with a 5.8- or a 6.5-foot bed. Be aware that not all trim levels are available with all configurations. All cab configurations are available with four-wheel drive.rnBase Sierras are fairly bare-bones, which is fine if you're looking for a work truck. It comes with a 4.3-liter V6 (285 horsepower, 305 pound-feet of torque), though a 5.3-liter V8 (355 hp, 383 lb-ft of torque) is optional. For any kind of regular use, you'll want more creature comforts than the base Sierra delivers as standard.rnThe SLE trim level adds a backup camera, an upgraded infotainment unit, 17-inch aluminum wheels, and a leather-wrapped steering wheel with an optional telescoping column.rnStepping up to the SLT, our trim level of choice, nets you the 5.3-liter V8 engine, towing hardware, power-folding and heated mirrors, and heated leather seats. The SLT's standard V8 engine paired with the available eight-speed automatic forms our preferred Sierra powertrain. A 6.2-liter V8 (420 hp, 460 lb-ft of torque) becomes an option at the SLT level. Parking alerts become available, too, and they're terrifically handy in a full-size pickup.rnAt the top of the range is the Denali, which comes with most of the features available on lower trim levels and has all of the available driver assistance features. It adds exclusive Magnetic Ride Control dampers, 20-inch wheels and unique interior appointments.Integrated Trailer Brake Control,On Star,Automatic Headlights,Bluetooth For Phone,Bose Premium Audio Speaker System,Dual Illuminated Vanity Mirrors,Engine liters: 6.2,Front Fog Lamps,Full Size Spare Tire: Std.,Garage door transmitter: HomeLink,Heated/Ventilated Driver & Front Passenger Seats,Heavy-Duty Trailering Package,High-Intensity Discharge Headlamps,Inside Auto-Dimming Rear-View Mirror,Intermittent Wipers - Variable,Locking Differential,Navigation System,Pickup Truck Cargo Box Light,Power Folding & Adjustable Heated Outside Mirrors,Power Locks,Power Mirrors,Power Seats,Power Tilt-Sliding Sunroof w/Express-Open/Close,Power Windows w/Driver & Front Passenger Express-Down,Power-Adjustable Pedals w/Memory,Radio: AM/FM Stereo w/CD Player & MP3 Capability,Rear Window Defogger: Std.,Rear-View Camera System w/Navigation Display,Remote Keyless Entry w/2 Transmitters,Remote Vehicle Start,Second Row Folding Seat,Separate Driver/Front Passenger Climate Controls,Skid Plate: Opt.,Sliding Rear Window,Splash Guards,Steering Wheel Mounted Controls,Telescoping steering wheel,Theft-Deterrent System,Tilt Wheel,Tire Pressure Monitor,Towing pkg,Ultrasonic Rear Parking Assist,USB Port Audio System Feature,Variable Effort Power Steering,Vehicle Stability Control System,Wireless connectivity,XM Satellite Radio,Air bags, dual-stage frontal, driver and right-front passenger and head curtain side-impact, front a,Airbags - Head For 2nd Row Seats,Airbags - Head For Front,Anti-lock braking system (ABS),Child safety rear door locks
