RV Industry Association Board Delays Model Year 2028 GMI Enforcement Date

During its meeting this week, the RV Industry Association Board of Directors made the decision to delay the implementation and enforcement date of the grounding monitor interrupter (GMI) requirement for new RVs. When the Board initially voted to adopt the GMI requirement for new RVs back in June, the Standards Steering Committee (SSC) felt that there would be sufficient availability of GMI devices for use in RV manufacturing to meet the January 1, 2027 effective date and mandatory enforcement for model year 2028 production. 

As the SSC continued to monitor the availability of GMIs throughout the summer and fall, it became clear that there is still a lack of fully developed, listed GMIs. Based on this feedback, the Board determined that the previously established enforcement deadline for model year 2028 is no longer feasible given these current supply chain realities and testing constraints. 

Industry leadership emphasized that allowing sufficient time for rigorous, real-world testing of this new electrical technology is essential to ensure that the consumer experience and safety is not negatively impacted. RV manufacturers have actively prepared for integration, but comprehensive production validation cannot occur until listed devices are widely accessible.

The Board of Directors will continue to monitor supplier progress of listed GMI availability and will formally revisit the implementation schedule and discuss next steps at its upcoming February Board meeting. The Board reiterated its commitment to selecting a new date for implementation and enforcement as soon as sufficient availability of listed GMI devices from multiple suppliers is confirmed.
