Toyota Motor Corporation introduced its light truck named Toyota Stout (Toyota RK) in April 1954.
First Generation (RK)
In 1954, Toyota launched its Toyopet RK 1 ¼ ton truck, which was a bit larger than the Toyota SG light truck and smaller than the Toyota FA medium duty truck. A minor upgrade was made in 1955 to raise its capacity to 1.5 tons.
It was available as a 2-door, 3-seater standard pickup body having a separate well body. Some of the other body styles offered were: a van, an ambulance, double cab coupe utility (2-doors, 6-seater, integral well body), drop-side pickup, pickup with stake sides, a pickup with full height metal side with a canvas top, a light bus and an ice cream van.
The mechanicals offered in all the models were almost similar to the one found in new vehicles at that time like ladder frame chassis, leaf springs, solid axles, and 4-wheel drum brakes. The engine offered was a 48 hp 1500cc Type R with manual transmission. Some of the other features were windscreen wipers, dual outside mirrors introduced in 1955, hubcaps, chrome trim and dual headlights.
The first production unit of RK was indicated as 1 ¼ ton truck, while it could carry 1220 kg and the later model that was rated as 1.5 ton truck could in fact carry 1330 kg.
The RK was redesigned in 1957 and two new variants RK30 and RK35 were introduced. The company renamed the RK as Stout in May 1959. The major rival of the truck at that time was Nissan Junior.
Second Generation (RK45, RK100, RK101)
Second generation model was a complete revised version that was introduced in 1960. The Japanese market received two versions RK45 and RK100, both were powered by 1453 cc Type R engine and the 1897 cc 3R-B engine respectively.
In September 1967, the truck was exported for the first time as RK101. In 1968, the RK101 was replaced by Hilux in the North American market. However, in many other countries like Southeast Asia and Australia, it was offered alongside the Hilux. The engine used in RK101 was a 1994 cc 5R engine.
The second generation Stout received some traditional mechanicals components including leaf springs, 4-wheel drum brakes and a ladder frame chassis. It was offered in a pickup (2-door, 3-seater), a double-cab pickup (4-door, 6-seater) and a 2-door van body styles.
Third Generation (RK110)
In March 1979, the third generation Stout was launched with more contemporary looks and seemed to be like a smaller Hilux. The third generation Stout also received the same 1994 cc 5R engine.
The RK110 was available two body styles including a pickup (2-door, 3-seater) and a double-cab pickup (4-door, 6-seater). The production of the Stout was stopped in 1980s without offering any successor. However, few people think T100 and the Tundra as its successors but in fact both these vehicles were only made for North American market.
