The M6 Bomb Service Truck, unlike many other trucks in its family, had an open cab with no solid roof and no doors.
It normally had a canvas roof over the driver's compartment.
In hotter areas, the canvas roof could be removed and the windshield folded down for extra ventilation.

It had a rear area where it could carry ammunition, since it could be used in ammunition dumps to carry ammunition around the dump.
The M6 also was equipped with a winterization kit that included: an insulated battery box with a heating coil, a gasoline heater to heat the battery, and a petcock for the bottom of the fuel tank (for easy releasing of cold air and pressure from the gasoline tank).
