Pickup trucks continue to be the best selling vehicles in the country because of their versatility. Around here, you hear the term “Texans love their trucks” because Texas is easily the largest truck market in the country. Because we consider them our family vehicles, light duty trucks are the biggest sellers. However, when you need power, towing capability, interior room and comfort nothing beats a big HD truck. One of the stars in that arena is the GMC Sierra Denali with the 6.6 liter Duramax turbo diesel engine. To say that this truck is nice would be an understatement.
The Sierria Denali is the truck that the boss usually drives home every day and then to his worksite. However, sometimes the boss has to bring supplies, tow a loaded equipment trailer to the job site, or pull another truck out of the mud. That is where the Sierria Denali 2500 really shines.
The Sierria Denali 2500 has an amazing towing capability of 23,000 lbs., conventional-hitch trailering capacity of 18,000lbs., and maximum payload of 7,215lbs. The Denali 2500 has an array of trailering features including trailer sway control, integrated trailer brake control, hill start assist, automatic grade braking, exhaust brake, and intelligent brake assist. When you are towing, the engine’s exhaust brake feature lets the engine slow the truck on down hills and saves a lot of brake wear.
I averaged a little over 18mpg during the week I had the Denali 2500. That is why the diesel engine is so important. There is no way a gas engine gives that fuel economy and power. The truck’s 36 gallon tank allows 680 miles of travel between fill-ups. And it really did!
The Sierria Denali’s interior is both luxurious and comfortable. The soft Nuance perforated power leather seats make any trip a good one. This truck is loaded with standard features such as GM’s AM-FM-Sirius XM stereo with CD/DVD player, Back up camera, MP3 plugs, USB connectivity, Bluetooth, Navigation, OnStar, rain-sensing wipers, leather-wrapped heated steering wheel and dual zone A/C. Optional goodies include: driver information center, rear-seat entertainment system, remote start, power sunroof, power sliding rear glass, and vehicle WiFi.
Sierra Denali HD models are offered only in the crew cab body style, in regular-and long-box configurations and in 2WD or 4WD.
The Denali’s bullet-hole chrome grille, chrome trim and body-color bumpers makes the truck instantly recognizable.
Sierra Denali HD is loaded with safety goodies such as StabiliTrak electronic stability control, OnStar, and airbags all around.
One thing I didn’t like about the Sierria Denali is the lack of A/C vents for the rear seats. It needs them on hot Texas days. Also, this truck is a little long in the tooth. GMC’s has a new truck coming soon, but it needs to be here now to keep up with the competition from Ford and Ram, who have already updated theirs.
Overall, the GMC Sierria Denali 2500 4WD Crew Cab is a great truck for someone that needs the ultimate in luxury, capability, and durability.
