        321.123  TRAILERS.
         1. a.  All trailers except farm trailers, mobile homes, and
      manufactured homes, unless otherwise provided in this section, are
      subject to an annual registration fee as follows:
         (1)  For trailers with an empty weight of two thousand pounds or
      less, the annual registration fee is twenty dollars.
         (2)  For trailers with an empty weight in excess of two thousand
      pounds, the annual registration fee is thirty dollars.
         b.  Trailers for which the empty weight is two thousand pounds
      or less are exempt from the certificate of title and lien provisions
      of this chapter.
         c.  For trailers and semitrailers licensed under chapter 326,
      the annual registration fee for the permanent registration plate
      shall be the applicable fee under paragraph "a".  The
      registration fees for a permanent registration plate, at the option
      of the registrant, shall be remitted to the department at five-year
      intervals or on an annual basis.  Fees collected under this section
      shall not be reduced or prorated under chapter 326.
         2. a.  Travel trailers and fifth-wheel travel trailers, except
      those in manufacturer's or dealer's stock, shall be subject to an
      annual registration fee of thirty cents per square foot of floor
      space computed on the exterior overall measurements, but excluding
      three feet occupied by any trailer hitch as provided by and certified
      to by the owner, to the nearest whole dollar.  When a travel trailer
      or fifth-wheel travel trailer is registered in Iowa for the first
      time or when title is transferred, the annual registration fee shall
      be prorated on a monthly basis.  The annual registration fee shall be
      reduced to seventy-five percent of the full fee after the vehicle is
      more than six model years old.
         b.  A travel trailer may be stored under section 321.134,
      provided the travel trailer is not used for human habitation for any
      period during storage and is not moved upon the highways of the
      state.  A travel trailer stored under section 321.134 is not subject
      to a manufactured or mobile home tax assessed under chapter 435.
         3.  Motor trucks or truck tractors pulling trailers or
      semitrailers shall be registered for the combined gross weight of the
      motor truck or truck tractor and trailer or semitrailer, except that:

         a.  Motor trucks registered for six tons or less not used for
      hire, pulling trailers or semitrailers used by a person engaged in
      farming to transport commodities produced by the owner, or to
      transport commodities or livestock purchased by the owner for use in
      the owner's own farming operation or used by any person to transport
      horses shall not be subject to registration for the gross weight of
      such trailer or semitrailer provided the combined gross weight does
      not exceed twelve tons, plus the tolerance provided for in section
      321.466.
         b.  Motor trucks registered for six tons or less not used for
      hire, pulling trailers or semitrailers used by a person in the
      person's own operations shall not be subject to registration for the

      gross weight does not exceed eight tons, plus the tolerance provided
      for in section 321.466.
