Best vehicles for stealing/taking crates and barrels?

I've already tried the cargo helicopter, but the fact that it has no weapons (not driver controlled), and is too big for the oil Factories (leading to the destruction of the propellers almost always, for 4 crate spaces is not really balanced) Because I would be interested in a vehicle, with more than 1 space for boxes, and that can attack, and not big like the cargo, It It exists (ik about boats, but i woloud like more Land/Flying ones)
