A conventional cargo or passenger-type van (typically about 14-24 feet in length) is fitted with a boom assembly that is readily transported with the van in a collapsed position and substantially parallel to the van roof, but can be elevated to a substantially vertical position, and quickly extended upwardly to full height. Where four booms are used, full height may be about 65 feet, or even more. A support frame is provided which substantially supports a main pedestal exteriorly of the roof and connected to the booms and an extension cylinder, to the van's main frame, including initially telescopic support posts disposed inside the van interior which do not impede access to the van interior from the side and rear doors, and which leave the center of the van interior essentially unobstructed. A pivotal connection for the first boom about which it moves from a transport to a substantially vertical position is mounted slightly to the rear of the centerline of the rear axle of the van. A removable equipment mounting end cap containing whatever equipment is desirably elevated by the booms is mounted on the most vertical (when extended) of the booms.
