  • Analyze upfitter body specifications and convert them into chassis engineering requirements.
  • Maintain a library of 2D drawings that include critical dimensions for supporting logistics operations.
  • Perform packaging studies to integrate Upfitter Specific devices such as liftgates, ePTOs, battery boxes, etc.
• Documentation:
  • Define and maintain approved upfit configurations, compatibility guidelines, and best practices.
  • Coordinate design changes with upfitters when the design update affects the integration with the upfit/body.
  • Maintain traceability records documenting ‘clean points’ for when a design change was cut in (applies to both chassis and body changes).
  • Drive continuous improvement of the Stripped Chassis Body Builder Guide by providing technical feedback from lessons learned.
  • Develop configuration rules, constraints, and documentation to guide quoting and ordering.
• Continuous Improvement:
