A King Cab is a pickup truck with a smaller rear seating area behind the front seats, giving you more cabin space than a regular cab without going to a full four-door crew cab. The name “King Cab” is Nissan’s trademark for what the broader truck industry calls an extended cab. Datsun (Nissan’s former brand name) introduced the first King Cab in 1977 as the first extended cab pickup on the market, and the nameplate has stuck with Nissan trucks ever since.
How a King Cab Differs From Other Cab Styles
Pickup trucks come in three basic cab configurations: regular cab, extended cab, and crew cab. A regular cab has a single row of seating and two doors. A crew cab has two full rows of seating and four full-sized doors. The King Cab sits in between. It has a small rear seating area accessed through smaller, rear-hinged doors that swing open only after you open the front doors first.
Every major truck manufacturer offers this in-between size but calls it something different. Ford uses “SuperCab,” Ram calls it “Quad Cab,” Toyota uses “Access Cab” on the Tacoma, and GM has used both “Extended Cab” and “Double Cab.” They all describe roughly the same concept: extra space behind the front seats without committing to a full second row.
Rear Seating and Interior Space
The rear area of a King Cab is functional but tight. On the Nissan Frontier, rear legroom measures about 26.2 inches, which is noticeably less than what you’d find in a crew cab. The rear seats are designed as a two-passenger bench with a flip-up cushion, so they fold away when you don’t need them. This lets you use the rear area as extra covered storage instead of seating.
In practice, the back seats work fine for short trips with smaller passengers or kids in car seats, but adults will feel cramped on anything longer than a quick ride across town. Most King Cab owners treat the rear space as a flexible zone: seats down for passengers when needed, seats folded up for groceries, tools, or anything you want to keep out of the weather and away from the open truck bed.
Bed Length and Cargo Advantages
Because the King Cab’s cabin is shorter than a crew cab’s, the truck can pair a longer bed onto the same overall frame length. This is one of the main practical reasons people choose them. If you regularly haul lumber, sheet goods, equipment, or anything that benefits from extra bed length, a King Cab gives you more usable cargo space without needing to step up to a longer wheelbase truck that’s harder to park and maneuver.
On crew cab trucks like the Nissan Frontier, the standard bed is about 59.5 inches long. A King Cab on the same platform typically offers a longer bed within the same overall footprint, making it a better fit for work use where hauling matters more than rear passenger comfort.
Payload and Towing
The shorter cabin also means the King Cab weighs slightly less than its crew cab counterpart, which translates into marginally better payload and towing numbers. On the Nissan Titan, for example, the King Cab offers a maximum payload of 1,613 pounds compared to the Crew Cab’s 1,607 pounds, and towing capacity edges up from 9,317 pounds to 9,323 pounds.
These differences are small enough that they won’t be the deciding factor for most buyers. But they illustrate the tradeoff at work: less cabin weight means more capacity for cargo. If you’re regularly loading near the truck’s maximum limits, those extra few pounds of payload can matter.
Who a King Cab Is Best For
King Cab trucks appeal to a specific type of buyer. If you mostly drive alone or with one passenger, rarely need rear seating for adults, and want maximum bed space for hauling, the King Cab configuration makes more sense than a crew cab. They also tend to cost less than crew cab versions of the same truck, since you’re getting less interior space.
Contractors, tradespeople, and weekend haulers who prioritize bed length over backseat room are the classic King Cab buyers. The rear area still gives you a lockable, weather-protected storage space behind the front seats for tools, bags, or valuables you wouldn’t want sitting in an open bed.
On the other hand, if you regularly carry a family or adult passengers in the back, a crew cab with full-sized rear doors and proper legroom will be far more comfortable. The King Cab’s rear-hinged doors and limited legroom make loading passengers and car seats less convenient, and long rides in the back are genuinely uncomfortable for anyone with legs longer than a child’s.
