By Bruce W. Smith When it comes to hard-core work/tow vehicles, there’re only three brands from which to choose: Dodge, Ford, and GM. Then you get into brand loyalty, and it’s hard to break out of the family tradition if it’s been established the General, Blue Oval, or a Ram is what the family drives. But I bet Uncle Charlie would love this new Silverado even though he says he’s a die-hard Dodge man. Those were
the thoughts flitting around in my head as I glide past slower traffic
while powering up a long, steep highway grade with a big 24-foot, Ranger
center-console fishing boat latched to the hitch of the 3500 Chevy
Silverado Crew Cab 4x4 I’m driving. The Ranger’s 5,000 pounds of towed
weight hardly taxes the Duramax My foot rolls deeper into the throttle and the speedometer needle climbs at a very satisfying pace—obviously a direct result of having 660-foot-pounds of torque rolling off the crankshaft of the 6.6L Duramax V8 diesel humming from beneath the hood. Back off the throttle and the Silverado settles down to a smooth, steady, quiet cruise speed of 65mph—uphill. It’s a remarkably powerful—and comfortable—pickup. Gary White, GM North America vice president and vehicle line executive of full-size trucks—and one of my driving partners—says “There’s not a broader, more powerful or more capable lineup of heavy-duty pickups in the industry.” DURAMAX STENGTH One of the
very first things we noticed on the 3500 Dually is all of GM’s Heavy Duty
pickups are equipped with a
The top-of-the-line Silverado LTZ we tested for two weeks here at Truck Test Digest was optioned out with a lot of upgrades. The most beneficial—and expensive—to towing is upgrading from the standard 6.0 Vortec gas V8 to the Duramax diesel ($7,195) and the Allison six-speed automatic ($1,200.) The 365hp Duramax 6.6L turbo-diesel is the most powerful diesel in the 3/4- and 1-ton pickup market with an impressive 660 lb.-ft. of torque. All of that power rolls in early in the rpm range, so it’s a superb package for towing really big loads, like multi-horse trailers, 5th wheels, big tow-behind travel trailers, and yarding around farm and construction equipment. GM’s torque
monster Duramax is also one of the cleanest on the road in 2008. Charlie
Freese, the Executive Its cleanliness is quite evident when you’re following a Duramax-powered Silverado because there’s not a hint of black smoke, nor any hint of unburned diesel fuel as the truck accelerates. Fuel economy isn’t quite as good as we’d hoped. But then none of the big diesels we’ve tested deliver stellar performance in that arena. We saw consistent mid-12s in city traffic, and mid- to upper teens (15-16) on the open road cruising 70. A note here: We dropped our speed to 60 and picked up 2mpg, which shows you that with a big pickup such as this it pays to drive slower in order to save at the pump. LUXURY INTERIOR During our two-week testing stint here on the Mississippi Gulf Coast we put on more than 600 miles driving city streets, country roads and interstates. Such seat time gives you a good appreciation for the interior comfort and spaciousness of the Crew Cab LTZ. The LTZ has
the upscale interior with the leather seating and power everything at your
command. It’s the kind of Our test truck also had the optional power sliding rear window ($200), ultrasonic rear parking assist ($245)—a must for the long-bed Dually; power sliding sun roof ($795)—that we could have done without; adjustable pedals ($120)—a definite must-have; and upgraded stereo system with 6-disc CD/MP3 player ($300)—a definite must as well. We also loved having the integrated factory brake controller ($200) that makes towing trailers equipped with electric brakes a lot smoother than typical with aftermarket controllers. Another aspect of the Crew Cab interior that we really like the one-hand flip-up/down rear split bench—very easy to open up that floor space when you have an arm full of stuff and need somewhere to unload it in a hurry. Those living in the snow belt will find favor with the heated windshield washer fluid system more effectively removes bug spatter and thin layers of ice and frost. When the system is activated, washer fluid is heated to 150 degrees F (60 C) or more
However, it’s the outside where most people will see the biggest changes in the Heavy Duty 3500 Silverado. The 2008 shares the same look as the ‘07s, which is when GM did a complete sheetmetal change. The front sheetmetal of the Dually diesel conveys a much greater sense of power than it’s ½-ton counterparts. The grille is much more open than found on the 1500 Series and the hood is taller and vented close to the windshield on each side. The headlights are slightly larger, and the front fenders wider and more rounded–all working in concert to convey a broad-shouldered, muscular look which both Keith and I like. By the way, the Dually has a one-piece stamped fender, which really helps smooth its distinctive lines and doesn’t look like something just added on to accommodate te dual wheels. A one-piece wheelhouse and inner box side offer strength and a smoother, more integrated appearance. The boxes are 1.18 inches (30 mm) deeper in the front and 1.57 inches (40 mm) deeper at the rear than previous-generation models, with stronger inner walls that offer improved performance when fitted with ladder racks, tool boxes and other accessories. Speaking of
that, the long bed (8’) model we tested has a whopping cargo bed volume of
75.5 cubic feet. That’s as much cargo space as some pickups and SUVs have
in their entire interior. All Dually models feature marker lights on box side panels and sleek cab roof lights that are aerodynamically integrated into the top of the cab. That gives the Dually instant appeal to truckers! The tailgate designs include a lock and an available EZ Lift feature, with torque-rod assist. The tailgates are also easily removed by simply opening to 45 degrees and pulling straight out and away from the vehicle. Speaking of truckers, one of the new features available this year is fleet-model Duramax diesels are enabled at the factory to run on B20 bio-diesel fuel. That should help keep fleet operating costs down with the continually escalating costs of diesel fuel. As for costs, the base price for our Dually Silverado 4x4 listed at $40,390. As tested, with all the bells and whistles, the MSRP totaled $52,430. That price tag is up there. But as we noted on the radio show, this is the executive’s or full-time RVer’s Dually. It’s rich in looks and power, just like we think the owners of such a pickup will be. –Bruce W.
