2006 GMC Sierra 1500 SLE2 4dr Extended Cab SB 6.5 ft.

The 2006 GMC Sierra 1500 SLE2 Extended Cab SB measures 230 inches in length, with a 143-inch wheelbase, meaning the cargo bed expands to 6.5 feet long in this trim. The rear-wheel-drive, half-ton pickup is powered by a 295-hp, 5.3-liter V8 and 4-speed automatic, but a 6.0-liter, 345-hp V8 is available, along with a flex fuel version of the 5.3-liter V8. Fuel economy averages 16/19 mpg. The pickup rides on a short and long arm front and solid live axle rear suspension and uses 17-inch steel wheels with all-season tires. Larger 20-inch wheels are available.

The bed comes with tow hooks, but a trailer hitch is an extra feature. Fully equipped, the 2006 Sierra 1500 SLE2 Extended Cab SB can tow 10,400 pounds. It has two rows of seats, though the rear seat is limited and has only 33.7 inches of legroom. The rear passenger doors are undersized and open in conjunction with the front doors. Full power features include a power driver's seat, remote entry, heated extendable mirrors, a CD player, cruise control, and intermittent wipers. Leather steering-wheel trim, a front power outlet, a tachometer, and a temperature display and compass are also standard. Options add audio controls in the backseat and on the wheel, satellite radio, leather upholstery, memory settings for the driver's seat, automatic climate control, a CD changer, and a power sunroof.

Safety equipment is fairly minimal, but this Sierra does feature dual front airbags with passenger sensors, 4-wheel ABS brakes with electronic brakeforce distribution, a front stabilizer bar, automatic headlights, foglights, and an auto-dimming rearview mirror. Traction control is available as an option. Auto-dimming side mirrors also cost extra, as does an adjustable suspension, regenerative braking, OnStar, mirrors with turn signals, a locking rear differential, and skid plates.
