TITLE: FMVSR INTERPRETATION

TEXT: This is in response to your January 29, 1976, letter to Secretary Coleman, concerning problems with your 22 foot Executive "MINI" Motorhome.

@@ 567.4(g)(3) and 567.5(a)(5) of 49 CFR Part 567, Certification, provide that a motor vehicle's Gross Vehicle Weight Rating (GVWR) shall

not be less than the sum of the unloaded vehicle weight, rated cargo load, and 150 pounds times the vehicle's designated seating capacity.

Your letter and its enclosures indicate that your vehicle's weight is 9180 pounds, its designated seating capacity is six, and the GVWR specified by Executive is 9000 pounds. From this information, there appears to be a violation by Executive of Part 567. In addition, the possibility that the rear axle may be overloaded under normal conditions of use may constitute a defect related to motor vehicle safety. I have forwarded your letter to our Office of Standards Enforcement for such further action as may be appropriate.

Please note that a final-stage manufacturer is not automatically prohibited from certifying a GVWR that differs from that specified by the chassis manufacturer. For the purposes of the Federal motor vehicle safety standards and regulations, Executive is free to certify a lower GVWR, provided the above-cited constraint is observed.

The remaining questions presented in your letter are not matters over which we have jurisdiction, and probably are most appropriately handled by a private attorney.
