The Bolivar seems to be the PLAV version of the VZA's Capuchin. It is rare, and unlike the Capuchin, it is never used for roadblocks.
It is not available for purchase from any faction.
Its rarity, along with a lack of weapons, armor and speed, means it has little practical use.
Both the Capuchin and Bolivar series are based on the American M-35 A3 cargo truck.
The Bolivar is named after Simón Bolívar, a national hero in Venezuela.
