The full line of Isuzu trucks and sport utility vehicles from 1981-96 is comprised of five models: Pick-up (the earlier models were known as P'UP), the Trooper/Trooper II, the Amigo, the Rodeo, and the Hombre.
The Pick-up truck is a 2-door conventional style pick-up vehicle with an open rear bed designed for transport of materials. The Pick-up is the only truck in the Isuzu line of trucks which has been produced since 1981. Throughout the Pick-up's production years, it has been available with several engines, including the 4-cylinder 1.8L, 2.2L diesel, 2.0L, 2.3L and 2.6L engines, as well as the V6 3.1L, which was manufactured by General Motors. The Pick-up truck has been available with 2-wheel or 4-wheel drive. The Isuzu manufactured Pick-up was last available in 1995; the Hombre takes over this position in 1996.
The Trooper/Trooper II, which is the second vehicle to enter the Isuzu truck line-up, was introduced in 1985. The Trooper and Trooper II are the same vehicle; in 1992 the Trooper II dropped the II and simply became the Trooper. The Trooper is a large, 2 or 4-door sport utility vehicle with a squared back end (in contrast to the Rodeo). The rear doors are of the conventional swing open-type, with the right-hand door being smaller than the left-hand door. The Trooper is also equipped with 2-wheel or 4-wheel drive. The Trooper has come equipped with a 2.2L diesel, 2.3L, 2.6L, 2.8L V6 (manufactured by General Motors), and 3.2L V6 engine.
The Amigo, which was introduced in 1989, is a short wheel based, 2-door sport utility vehicle. The Amigo is equipped with a removable top and a has a rear bed which accommodates a rear seat. The rear seat could be removed to carry additional cargo. The Amigo is only available with 2 engines: the 2.3L and the 2.6L. The last year the Amigo was available is 1994.
The Rodeo, at first glance, seems to be a merging of the Trooper and the Amigo models. The Rodeo is a large, 4-door sport utility vehicle much like the Trooper. The rear end on the Rodeo is slanted and the rear door is a hatch, which swings up. The Rodeo was first introduced by Isuzu in 1991 and is still produced. This vehicle has been available with three engines. In 1991 the Rodeo was available with 2.6L and 3.1L engines, whereas in 1992-96 the vehicle came equipped with the 3.2L V6. The Rodeo also comes available with 2-wheel and 4-wheel drive.
Since the Isuzu Pick-up was dropped after 1995, Isuzu decided to sell a 2-wheel drive version of the S-10 Chevrolet truck and rename it the Hombre. The Hombre's 2.2L engine is manufactured by General Motors. The Hombre is a conventional pick-up truck, like the Isuzu P'UP.
