11 Inspection of motorhomes

Vehicle inspection requirements manual references

This bulletin gives guidance to vehicle inspectors in applying the following requirements in the VIRM: Entry certification:

Application

This bulletin applies to the structural inspection of motorhomes undergoing entry certification in New Zealand. It covers the specialist certification requirements for motorhomes undergoing entry certification.

For motorhomes with overseas compliance covering the motorhome conversion, refer to Technical bulletin 41:Entry certification procedures for certain modified vehicles. Exhaust emission standard compliance can be verified by one of the methods specified in Technical Bulletin 28.

Structural inspection

If a motorhome is of a van body type (monocoque construction), it will need to have the trim removed to enable a full structural inspection. If this is impracticable, the entry certifier/vehicle owner may apply to the Transport Agency for an exemption from trim removal requirements (see Reference material 18).

If a motorhome is of a cab/chassis body type with the body mounted on the chassis, the vehicle inspector is only required to visually inspect the vehicle (without disassembly) to ensure general safety requirements are met. However, if the motorhome body contains designated seating positions with certified seatbelt mountings (as is required for most motorhomes built after October 2003), it will need to have the trim removed to enable a full structural inspection. If this is impracticable, the entry certifier/vehicle owner may apply to the Transport Agency for an exemption from trim removal requirements (see Reference material 18).

Specialist certification

Generally, any modifications or repairs to a motorhome that may affect the structural integrity of the vehicle will require specialist certification.

Where vehicles are converted to motorhomes, specialist certification is required unless the vehicle owner can provide documented evidence proving that the modification was a ‘manufacturer’s conversion’.

Examples of modifications or repairs to a motorhome that will normally require specialist certification are:

  • cutting of the roof or bulkhead
  • lengthened chassis rails
  • installation of seatbelt anchorages
  • modification or strengthening of chassis components.
