Truck Cab Guide Regular or Single Cabs have two doors and no back seat for passengers. These are the smallest of all of the cab sizes.Extended Cabs have a backseat and extra rear doors that usually open in the opposite director (also known as "suicide" style). However, many truck manufactures are making these rear doors and are adding door handles to the rear doors as well. For most cabs of this type, the rear doors are not as big as the front doors.Crew Cabs also have rear doors and a larger back seat than Extended Cabs. The rear doors open in the same direction as the front doors, but the rear doors are still usually smaller than the front doors, but noticeably larger than Extended Cab rear doors.Only a few manufactures have versions of their trucks are slightly larger than the traditional Crew Cabs and these are considered Extended Crew Cabs.
