The trucks are called 'Technicals' because.. they're not.??
Finescale actually had an article about scratching a gun for a somalie technical, which was some huge anti-aircraft gun, that i copied.

You could alternatively buy a Jeep for a tray mounted gun. the italeri 1/24 jeep or toyota kits have a 50 cal.
