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.
