Multiple embodiments are disclosed which display modularity for accomplishing multiple modes of operation for a utility vehicle. The utility vehicle (100) may include a rear cargo platform (450), a plurality of connection points (460) disposed in matrix and adapted to couple an item to the rear cargo platform, and three or more couplings (490) for adding a subsection (470) in a non-pivotable manner or pivotably coupling the rear cargo platform. The vehicle may be a four-wheeled vehicle that coverts to a six-wheeled vehicle by the addition of the subsection. The utility vehicle may include a subsection cargo platform which may be coupled to the rear cargo platform and may pivot rearward. The utility vehicle may include couplings for adding a second subsection.
