Cabin (truck)

There are usually three types of cabs in pickup trucks:

• Regular cab means a pickup truck with 2 doors.[2] It has a single row of seating and may seat one or two passengers.
• Extended cab means a cab with rear seating.[3] It can have two, three or four doors.
• Crew Cab means a 4-door truck cab.[3] Is sometimes called a double cab.

There are a few possible cab configurations:

• A sleeper (or sleeper berth or bunk) is a compartment attached to the cab where the driver can rest while not driving. It is frequently on long-haul semi-trailer trucks. They can range from a simple 2 to 4 foot (0.6 to 1.2 m) bunk to a 12-foot (3.7 m) apartment-on-wheels. It allows drivers to spend weeks on the road moving cargo.[4]
• Cab over engine (COE) or flat nose, where the driver is seated on top of the front axle and the engine like in a body style of a truck, bus or van. They came into use just before World War II.[5] Cabovers have a shorter wheelbase and good visibility.[5] COE's are still popular among medium and light duty trucks in the United States. To access the engine, the whole cab tilts forward, This contrasts with a conventional truck where the engine is mounted in front of the driver.
• Conventional cabs are the most common in North America and Australia. The driver is seated behind the engine, as in most passenger cars (coachwork types: coupe, convertible, fastback, hatchback, limousine, sedan car, SUV, station wagon, minivan, and van) or pickup trucks.[6] Conventionals are further divided into "large car" and "aerodynamic" designs, as opposed to underneath with no nose like in a cab over. A "large car" or "long nose" is a conventional truck with a long (6 to 8 foot (1.8 to 2.4 m) or more) hood. With their very square shapes, these trucks experience a lot of wind resistance. They typically consume more fuel. They also provide somewhat poorer visibility than their aerodynamic or COE counterparts. By contrast, Aerodynamic cabs are very streamlined. They have a sloped hood and other features to lower drag. The front doors are behind (and mostly above) the front tires. Access to a conventional cabin is commonly by steps at or near the fuel tank(s) behind the front tires.
