Suspension choice is key to the driving characteristics of the Silverado, while the cabin configuration (pure pickup WT/LT or luxury LTZ) is key to how you expect to use the truck and what you expect from it.

An LTZ interior mirrors those of GM's full-size sport-utilities and is modeled more like a big touring sedan than a truck. It's a smooth, cohesive design with a central console that rises to a wall of smallish white-on-black buttons you can't operate with mittens like those on the "pure pickup." The optional navigation system is up high for good viewing, intuitive in operation, and offers many choices in radio station memory. The LTZ cabin is available in three interior colors and, though it will show dirt faster, the lightest color gives the most luxurious impression.

On the other hand, the WT/LT version is more conventional truck with a more open floor area, space for junk all over, and no concerns that something might get scratched, scuffed or dirty. Modern electronics suggest hosing them out isn't a good idea anymore, but a shovel and stiff bristle brush should get it done.

The basic Z83 suspension is best chosen for budget constraints or if you plan to make modifications and throw away the stock parts. The Z85 is similar except that it uses better shock absorbers and is calibrated for how today's light-duty pickups are often used as daily transportation. The Z71 package is designed for off-highway use and makes maximum use of suspension travel to keep the wheels on the ground when on the trail or dirt roads; this off-road package frequently provides the best ride quality on anything worse than glass-smooth interstates. The Z60 street package replete with 20-inch wheels and low-profile tires is best used for the city but can be used on a dirt road. The NHT package is designed for maximum loads; ride compliance is good based on how much weight it can carry and tow but driving it around empty may be firmer (harsher) than you want for every day use.

All Sierras benefit from brakes much improved over earlier (pre-2007) models, whether they have the rear discs or drum brakes.

For 2008, drivers who tow will appreciate the optional integrated brake controller like that used on the Sierra heavy-duty trucks. (However, be sure your trailer brakes are compatible with it before choosing the option, as some electro-hydraulic disc conversions do not work with the integrated controller.)

The Silverado can be equipped for a towing capacity of as much as 10,500 pounds (a 4WD longer cab NHT without a long bed); typical maximum tow ratings for other models without the 6-liter/NHT are in the 8000-8900 pound range. If you want a 10,000-plus tow rating in a regular cab you have to look to Ford or Toyota. Remember these trailer weights are usually quoted for an empty truck with a standard-size driver (154 pounds) on board.

Those with limited vertical clearance either at home or in commercial garages should note that the 4WD version of Silverado 1500 extended cab and crew cab is fractionally lower at the roof and loading level than the 2WD version. Some pickup trucks add two to three inches in height for 4WD, and those inches could be critical in tight fits.
