Extended Cab Vs. Crew Cab – Know The Differences

Pickup trucks have become high-demand vehicles in the automotive industry since their advancement from being farm or construction vehicles. Most families now alternate their preference for family SUVs with extended or crew cabs.

As the demand for pickup trucks continues to soar in the market, vehicle enthusiasts have intensified the debate for the best truck between extended cab vs. crew cab.

Although both these cab sizes are produced by several manufacturers in the industry, they come with obvious distinctions. Let’s delve into discerning the major differences between them.

An extended cab is a type of pickup truck with either 2 doors or 4 doors, having an extra passenger seat at the rear. The two-door extended cab’s front seat is fashioned in a way that they bend forward to allow access to the rear passenger seat.

Conversely, the four-door extended cab is designed with two back doors, popularly referred to as “suicide doors,” which grant access to the rear passenger seat without a need to bend the front seat forward.

The extended pickup truck comes with a carrying capacity of up to 5 passengers. This type of truck was commonly used by farmers and construction workers to convey farm products and construction equipment alongside a few passengers.

Q: Should I get an extended-cab or Crew Cab?

Functionality is a key factor that determines the type of cab you should get. For instance, an extended cab is designed with two front-hinging doors that bend forward to accommodate passengers in the back seat.

However, some extended cab trucks have two extra smaller doors known as “suicide doors” for accessing the back seat. Whereas a crew cab is built with 4 equal-sized front-hinging doors, as well as large front and back seats that can accommodate up to 5 – 6 people at one go.

So, typically, a crew cab offers more room and comfort for all passengers alongside enough load-carrying capacity. Therefore, this would be best if you need a comfortable truck for both people and goods.

Q: Is a Crew Cab larger than an extended cab?

Yes, a crew cab is larger than an extended cab and a regular cab. In contrast, an extended cab is larger than a regular cab. While regular cabs are designed with two front-hinging doors and a 2 – 3 passenger seat, extended cabs offer an extra back seat for more passengers.

Meanwhile, crew cabs are built with the capacity to offer more interior space and legroom for the tallest passengers. With the 4 front-hinging doors, crew cabs create a wider entrance and exit opening for the driver and every other passenger.

Q: Why are Crew Cab trucks so popular?

Crew cab pickup trucks are so popular because most people acquire them for private use more than professional use. Like family SUVs, crew cabs have also become famous for family use, especially for conveying small-large family members for vacations and other outdoor activities.

Due to their spacious rooms and wide trunk space, crew cabs do not only accommodate more people, up to 6 passengers. They also allow families to convey large children’s toys, picnic items, as well as vacation luggage with ease.

Q: What does Ford call their extended cab?

The Ford extended cab is called Super cab, while the crew cab and standard cab are pickup trucks known as Super crew and regular cab, respectively. Ford manufactures some of the strongest extended pickup trucks in the market.

The F-150 is an amazing pickup truck that most extended cab lovers would choose over and over again. The truck offers a powerful 5.0L V8 Ti-VCT engine, 6 available powertrains, polished solid aluminum wheels of 20-inch, and a super-advanced co-pilot assist.

No doubt, the Ford F-150 ranks among the top ten extended cab pickup trucks in the market. Others include Toyota Tundra, GMC Sierra, Toyota Tacoma, Ram 1500, GMC Canyon, Nissan Titan XD, and Nissan Frontier.

Q: What are the different cab sizes?

The different cab sizes include the regular or standard cab, extended cab, and crew cab. The regular cab pickup truck is built with a single 3-seater and two doors, while the extended cab pickup truck is structured with 2 or 4 doors (including the 2 back suicide doors), as well as front and back seats. The back row is usually smaller with minimal legroom.

Lastly, the crew cab pickup truck is well built to overcome the limitations of both regular and extended cabs. The crew cab is designed with 4 large full-size doors and two rolls with 3-seater each.

This cab size offers more legroom to both front and back commuters, also with maximum comfort. Typically, this is a major distinction between crew cab vs. quad cab.

Q: Which extended cab has the most room?

Ford F-150 pickup truck is the extended cab with the most room. This is followed by the CrewMax (Toyota Tundra).

The 2019 SuperCab (F-150) pickup truck features an interior dimension of 40.8 inches and 40.3 inches front and rear head rooms, 66.7 inches and 65.9 inches shoulder room, 43.9 inches and 33.5 inches front and rear leg rooms, and 62.5 inches and 64.7 inches front and rear hip rooms.

Conversely, the CrewMax (Toyota Tundra 2021) features an interior dimension of 39.7 inches and 38.9 inches front and rear head rooms, 62.6 inches and 60.4 inches front and rear hip rooms, 65.7 inches and 65.5 inches front and rear shoulder rooms, as well as 42.5 inches and 42.3 inches front and rear leg rooms, respectively.

Q: What truck has the biggest backseat?

The SuperCrew Ford F-150 comes with the biggest backseat from the factory. The rear seat dimensions are as follows; 40.3 inches rear headroom, 65.9 rear shoulder room, 43.6 inches leg room, and 64.7 inches hip room.

Meanwhile, the front seat dimensions of all three cab sizes of Ford F-150 are the same. The Ram 1500 Crew cab also features rear-seat dimensions of almost the same measurement as the Ford F-150.

However, the measurements are; 39.8 inches rear headroom, 45.2 inches rear leg room, 65.7 inches rear shoulder room, and 63.4 inches rear hip room, respectively.

Q: How do I know if my truck is a Crew Cab or Double Cab?

Ascertaining whether you have a crew cab or double cab (also known as an extended cab) is quite easy. The difference between these pickup trucks depends on the sitting capacity and door architecture.

So, if you’re wondering, “What is a crew cab?” A crew cab is fashioned with 4 equal large-sized doors and two sitting rows for the front and back passengers, having a carrying capacity of up to 6 people.

On the other hand, the double cab or extended cab is built with either 2 doors only or 2 large front doors and 2 small rear “suicide doors.” These trucks can only accommodate about 5 people for maximum comfort.

While the 2-door double cab front seat is designed to fold forward in order to let passengers into the rear seat, the 4-door (suicide doors inclusive) double cab allows access to the back seat through the small back doors (suicide doors).

Final Words

This article has just drawn the thick line between extended cab vs. crew cab pickup trucks from several auto manufacturer brands. One common factor across the various trucks compared above was the existence of similar front interior dimensions.

However, the back door architecture and rear interior dimensions revealed the difference between the extended cab or quad cab/super cab and the crew cab or super crew, respectively. 

Undoubtedly, from the analysis above, the crew cab or super crew seems to be the best pickup truck for both personal and professional use due to its four equal-sized large doors and wider interior dimensions.
