Hey Folks!
That truck is NOT a duce and half, that is a five ton. Look at the gap between the rear of the front tire and the fender. There is room of the driver to step in between the tire and the rear of the fender.

- SHAWNcorrect roy, the chassis is a 5-ton, 6x6 M139 (modified)
- JimWeb
it was originally an M139C, then M139D - I assume the change came with the different launcher styles.
- JimWeb
The M139 itself is an uprated version of the M36 2.5-ton LWB chassis which is why it is often mistaken for a 2.5-tonner.
- Roy_A_LingleThe standard five ton cargo trucks had an axle gear ratio of 6.443:1
The M-139 C, D, and F models used for the Honest John system had an axle gear ratio of 10.26:1 for improved off-road traction. That may make two items that make the Honest John trucks different.
