5. The electric vehicle of claim 3 , wherein:
the utility cabinet directly contacts a rearwardly-facing exterior wall of the front cage that is interconnected with a roof of the front cage; and
the exterior wall, the roof, and an uppermost surface of the utility cabinet in a vertical direction cooperate to define a storage space accessible from the utility space.
6. The electric vehicle of claim 1 , further comprising an intermediate section disposed at least partially between the front cage and the flatbed in the longitudinal direction,
wherein:
the intermediate section includes an alcove aligned with the utility cabinet in the longitudinal direction;
the alcove defines an opening into the intermediate section in a lateral direction perpendicular to the longitudinal direction; and
the opening is closed off from the operator cabin.
7. The electric vehicle of claim 1 , further comprising an intermediate section disposed at least partially between the front cage and the flatbed in the longitudinal direction,
wherein:
the flatbed comprises a first sidewall that extends upwardly away from a rear floor of the vehicle in a vertical direction to at least partially define the utility space and a second sidewall arranged opposite the first sidewall that extends upwardly away from the rear floor in the vertical direction to at least partially define the utility space, and
the intermediate section includes a reinforcement beam that is interconnected with a roof of the front cage at one end thereof and interconnected with one of the first sidewall and the second sidewall at another end thereof opposite the one end.
8. The electric vehicle of claim 7 , wherein the reinforcement beam extends oblique to the one of the first sidewall and the second sidewall to define an obtuse angle between the reinforcement beam and the one of the first sidewall and the second sidewall.
9. The electric vehicle of claim 7 , wherein:
the reinforcement beam at least partially defines an alcove of the intermediate section that is disposed at least partially between the front cage and the flatbed in the longitudinal direction; and
the alcove defines an opening into the intermediate section in a lateral direction perpendicular to the longitudinal direction.
10. The electric vehicle of claim 7 , wherein:
the flatbed comprises a first guide rail interconnected with the first sidewall that extends upwardly away from the first sidewall in the vertical direction to define a first slot between the first sidewall and the first guide rail and a second guide rail interconnected with the second sidewall that extends upwardly away from the second sidewall in the vertical direction to define a second slot between the second sidewall and the second guide rail; and
at least one of the first guide rail and the second guide rail is directly interconnected with the reinforcement beam.
11. The electric vehicle of claim 7 , wherein the flatbed comprises:
a rear gate that extends between the first sidewall and the second sidewall in a lateral direction perpendicular to the longitudinal direction to at least partially close off the utility space;
a rear bumper extending rearwardly in the longitudinal direction away from the rear gate; and
a vice mounted to the rear bumper.
12. A method of making an electric vehicle, the method comprising:
forming a monocoque of the electric vehicle;
supporting at least one electric motor of the electric vehicle using the monocoque; and
supporting a utility cabinet including a plurality of drawers using the monocoque,
wherein forming the monocoque comprises:
defining a front cage that provides an operator cabin,
defining a flatbed positioned rearward of the front cage in a longitudinal direction that is open to the ambient environment and a defines a utility space located outside the operator cabin.
13. The method of claim 12 , wherein supporting the utility cabinet using the monocoque includes positioning the utility cabinet in the flatbed such that the utility cabinet is accessible from the utility space.
14. The method of claim 12 , wherein forming the monocoque includes forming the monocoque from composite materials.
15. The method of claim 12 , wherein forming the monocoque comprises defining an intermediate section disposed at least partially between the front cage and the flatbed in the longitudinal direction.
16. The method of claim 15 , wherein defining the intermediate section comprises forming an alcove aligned with the utility cabinet in the longitudinal direction that defines an opening into the intermediate section in a lateral direction perpendicular to the longitudinal direction.
17. The method of claim 16 , wherein forming the alcove comprises closing off the opening from the operator cabin.
18. The method of claim 15 , wherein:
defining the flatbed comprises providing (i) a first sidewall that extends upwardly away from a rear floor of the monocoque in a vertical direction to at least partially define the utility space and (ii) a second sidewall arranged opposite the first sidewall that extends upwardly away from the rear floor in the vertical direction to at least partially define the utility space; and
defining the intermediate section comprises forming a reinforcement beam and interconnecting the reinforcement beam (i) with a roof of the front cage at one end thereof and (ii) with one of the first sidewall and the second sidewall at another end thereof opposite the one end.
19. The method of claim 18 , wherein interconnecting the reinforcement beam with the roof of the front cage and the one of the first sidewall and the second sidewall comprises defining an obtuse angle between the reinforcement beam and the one of the first sidewall and the second sidewall.
20. The method of claim 18 , wherein forming the reinforcement beam comprises at least partially defining an alcove of the intermediate section that is disposed at least partially between the front cage and the flatbed in the longitudinal direction and provides an opening into the intermediate section in a lateral direction perpendicular to the longitudinal direction.
