The instrument package looks like a cross between a Corvette's and a traditional pickup's. It includes a large speedometer and tachometer flanked by four smaller gauges. All use pleasant, highly legible white-on-black graphics.

The sound-system control panel is located above the climate controls. The climate control system uses a rotary-dial layout that works perfectly. There are three 12-volt outlets at the bottom center of the dashboard for radar detectors, cellular telephones, laptop computers, and other accessories.

An LT Extended Cab we drove awhile back came with six-way power front bucket seats with seat heaters and memory. The doors lock automatically as soon as you pull away, a security feature that can be de-programmed at the dealership. The LT also comes with a lockable floor console large enough to hold a picnic lunch for a family of four; it comes with a reversible, removable cup holder tray and a storage nook in front of the lid. Air conditioning outlets and a set of drop-down cup holders are built in for rear-seat passengers. A compass is incorporated into the LT's overhead console, along with three storage areas for sunglasses, garage door opener, and small items. The door trim is a nice combination of vinyl panels and dotted velour that is soft and warm to the touch.

The back seat in the extended cab offers more room and comfort than we expected. When cargo capacity is more important than hauling passengers, the entire rear seat assembly can be removed with a wrench and lifted out through the door.

A more recent drive in a 1500 HD crew cab revealed a really comfortable truck. The back seats are roomy and comfortable, very similar to those in an uplevel Suburban. The seats were trimmed in handsome leather and they could be flipped down to provide a big, secure cargo area. This is a great truck for someone who wants a roomy rear seat with interior cargo space and big trailer-towing capability.

About the only thing we don't like about the Silverado interior is the design of the interior door handles, which swivel through an up-and-in arc, and felt loose whenever we used them. We'd prefer more resistance and a more positive feel.

OnStar, which is now standard on LT models, is a communications and location system that allows customers to call for 24-hour assistance. The system calls for assistance automatically if the truck's airbags have deployed.
