2007 Chevrolet Express LS3500 Ext.

This 3500 rides on the Express's extended 155-inch wheelbase, and all 3500s have a one-ton designation. Stability control is standard on all 3500 models.

Express models with the 3500 label upgrade to a 6.0-liter V8, which generates 300 horsepower and 360 pound-feet of torque. This larger V8 is paired with a four-speed automatic transmission, but it's a more heavy-duty version than that in the 1500. When the 3500 is equipped with the necessary tow-prep kit, it will haul up to 9,800 pounds.

The lower-level LS trim comes with a very basic set of included features, including air conditioning, an AM/FM radio, and an anti-theft system. Since the 1500 is intended as a fleet vehicle, there are no significant comfort and convenience upgrades available.
