Sometimes, a chase vehicle may be equipped with a trailer, which can provide a lot more room at the cost of being more difficult to maneuver. A pickup truck or van by itself can be a lot more maneuverable but at the cost of squeezing all the equipment, crew, pilot, and passengers into a single vehicle. Many chase vehicles are fitted with a cargo liftgate to aid in loading heavy equipment into the cargo space (the envelope itself can weigh 250 lbs or more).
Communication between the balloon and chase vehicle can be accomplished by two way radio, or even shouting, when they are close enough together. The use of cell phones for this purpose, while the balloon is flying, may violate local telecommunication laws and should therefore be avoided except in an emergency situation.
