A little more guidence would be nice:
Cargo truck is fairly broad, gas tanker truck? 2 1/2 ton troop carrier? HEMMT fire engine? 5 ton Guntruck? LRDG Chevy truck? 2 1/2 ton military truck converted to a civilian water tender, the semi from the Road Warrior etc
So I might be interested, I have lots of possible ideas but it depends on where you draw the line.
