Trucks used as 2pdr portee

[Attilio]

There is some confusion about the trucks used as 2pdr portee in North Afrika.
Had anyone the complete list of the different trucks used in this role in North Afrika?
In any vehicle the gun can fired from the rear of the truck?

Thanks
Attilio

I know that CMP cab 12 and Bedford QL were two that were used but I am not sure what other makes there were.
