2008 Chevrolet Silverado HD - Crew Cab & Extended Cab Second Row Seating

Compare the widths of the rear windows and armrests and you'll see the Crew Cab truck has more space in the 2nd row. There's another plus -- see the large hump in the middle of the Extended Cab truck? The Crew Cab's longer body allows for a lower driveline hump, offering more comfortable seating and easier hauling of large boxes and other cargo.
