ABSTRACT:
A vehicle with a variable-length wheelbase is disclosed. The vehicle of one embodiment has a first body portion coupled to a first set of wheels and a second body portion coupled to a second set of wheels to define a vehicle wheelbase. The first and second body portions are moveable relative to each other in a direction substantially parallel to a longitudinal axis of the vehicle, so as to move the base between extended and retracted positions. When the base is in the retracted position the vehicle's wheelbase has a first length, and when the base is in the extended position the wheelbase has a second length greater than the first length. A boom is pivotally coupled to the base. The boom moves toward a lowered position when the base is moved toward the extended position, and the boom moves toward a raised position when the base is moved toward the retracted position.
