Mule

The Mule is a cube van that is on all of the GTA III era games. It has no special purpose, and is on the games just as an essential vehicle. Two people can fit in the truck, as the rear part does not open. The rear part cannot be accessed unless the truck is sereously damaged, then the rear of the truck is exposed. Also a thing that can be mentioned is that because of the truck's akward weight division, this truck is very easy to flip.
