Who made the first 4-door truck?

Answer 1

The Frontier was introduced in 1997 for the 1998 model year as a replacement for the aging 1986.5-1997 Nissan Hardbody Truck. Nissan first offered the Frontier with a 4-cylinder engine, the KA24DE, but added the V6 engine, the VG33E in 1999. Elsewhere, the Frontier was also known as the Nissan Navara

That changed, with the introduction of the 2000 Frontier Crew Cab. The Crew Cab was the first compact pickup to offer a 4-door body-style in North America. Until that point, crew cabs were heavy duty versions of full-size trucks and were mainly used as commercial vehicles, although four-door compact pickups existed in Asia and Europe for decades.

For 2001, Nissan facelifted the Frontier, introducing bolder styling in an effort to make it more appealing to younger buyers in its second generation. The Frontier was completely redone after the 2004 model year, which later resulted in the suspension of the regular cab model, indefinitely.

Built in Japan from 1997 to 2000. Versions: Single cab, King Cab, Crew Cab (Introduced in 2000 and only available on 2000-current models). Engines: Petrol (KA24DE) and Diesel (TD27) (2wd and 4wd) with 5sp manual transmission. Also exported to Central and South America. US production in Tennessee started in 1998 with a Single cab and a King cab, a Crew Cab arrived in 2000. Also in 2000 a special edition was first offered called the Desert Runner. It had a king cab base but on the 4X4 frame which gave it a boost in ride height, bigger tires and a 4-speed 2WD drivetrain. In 2001 the Desert Runner got a new look and a supercharged version of the V6 engine.
