Historical: The GMC CCKW-352 and CCKW-353 were
the workhorses of the US Army in WW II. Immediately after
the war, the US Army turned its attention to redesigning
and modernising of the standardised 2½ ton truck.
Towards the end of the 1940´s a number of prototypes
were produced by Chrysler under the designation T55.
Although this project doubtless helped to show the
direction which the post-war 2½ tonner would take, in
itself it was a dead end, and in the beginning of the
1950´s, the Ordnance Department had drawn up a
specification for a new design of 6 x 6 chassis which
followed more conventional lines.
GMC, Reo and Studebaker all produced prototypes of what
they hoped would become the standard truck in the class.
GMC´s contribution first appeared in 1950, and was
powered by a petrol engine driving through a Hydramatic
twin range 8-speed automatic transmission. In basic cargo
form it was designated M135. It was also produced as
tractor (M221), water tanker (M222) and dump truck
Studebaker newer moved beyond the prototype stage. The
prototype was submitted for trials in 1949, but no series
production took place and later Studebaker became
involved in manufacturing the Reo design.
Reo Motors of Lancing, Michigan produced the M34 and the
twin rear-wheeled M35. It was a no-nonsense truck with a
conventional engine and drive-line lay-out.
The G742-series, dubbed the "Eager Beaver" by
Reo´s marketing department, was launched in 1951. The
initial contract called for 5.000 vehicles with
production start in early 1953.
The model continued, with periodic changes, in production
until the late 1980s and by that time more than 150.000
trucks had been produced.
Many body-types (dump truck, shop van, expansible shop van, tanker,
tractor etc.) existed on several chassis variants, and
some mounted with a 4.5 ton winch.
Over the years manufacturers like Studebaker, Curtiss
Wright, Kaiser Jeep, AM General and White also produced
large quantities of the G742 vehicles.
Later models had multi-fuel (Continental LDS 427-2, Continental
LDT-465-1, Continental LDT-465 D) and
diesel engines (Caterpillar 3116).
