Item 1.  Business

The Navistar Financial 2002-B Owner Trust (the "Trust") was formed pursuant to a
separate Trust Agreement dated as of November 19, 2002, among Navistar Financial
Retail Receivables  Corporation,  ("NFRRC"),  as seller (the "Seller") and Chase
Manhattan  Bank USA,  National  Association  (formerly  known as  Chemical  Bank
Delaware),  as owner trustee (the "Trustee").  Retail notes and related security
interests  in the  financed  vehicles  and a  beneficial  interest  in a pool of
commercial  retail  leases  financing  vehicles  (the "Retail  Contracts")  were
transferred  to the Trust in  exchange  for fixed or  floating  rate  notes (the
"Notes")  and  pass-through   certificates  (the   "Certificates")   which  were
registered on  Registration  Statement  No.  333-67112 and sold to the public in
reliance on Rule 415 under the Securities Act of 1933.

NFRRC is a wholly-owned  subsidiary of Navistar Financial Corporation.  Pursuant
to a Pooling and Servicing  Agreement or a Servicing Agreement (the "Agreement")
for each Trust, Navistar Financial Corporation acts as servicer (the "Servicer")
and, in that capacity,  manages, services,  administers and makes collections on
the  Retail  Contracts.  Each  Agreement  provides  that  collections  shall  be
distributed  to  noteholders  and   certificateholders  and  otherwise  used  in
accordance  with the priorities set forth therein.  Pursuant to each  Agreement,
the Seller  established a reserve account as credit  enhancement for each Trust.
Amounts on deposit in each reserve  account after  payments to security  holders
and the Servicer are paid to the Seller to the extent that such amounts exceed a
specified  reserve account target balance.  The specified reserve account target
balance  cannot,  however,  be less  than a  specified  minimum  of the  initial
aggregate receivables balance for each Trust.

Item 2.  Properties

Refer to Schedule 13 for information regarding the Certificates.


Item 3.  Legal Proceedings

The registrant knows of no material pending legal  proceedings  involving either
the Retail Contracts or the Trustee, or the Seller or Servicer in respect of the
Trust.


Item 4.  Submission of Matters to a Vote of Security Holders

No matter  was  submitted  during  the  period  of this  report to a vote of the
Certificateholders.

Item 5.  Market for the Registrant's Common Equity and
         Related Stockholder Matters

There were 29 participants  holding positions in the Certificates  issued by the
2002-B Owner Trust as of the end of the reporting year.  Below is a breakdown of
participants by Class:

Total                           29


There is no principal market in which such  certificates  are traded.  The Trust

At each Distribution Date, an annualized loss percentage is computed. If the
annualized percentage exceeds 1.5%, any monthly excess servicing is transferred
to the reserve account to 10.0% of the ending receivable balance. When the
annualized loss percentage falls to or below 1.5%, the reserve account
requirement returns to the greater of the specified target amount or the
specified minimum balance.

The annualized loss percentage is calculated as follows:
The numerator of which is equal to the sum of the aggregate losses plus
liquidation proceeds for each of the calendar months which are the fifth, fourth
and third calendar months preceding the calendar month immediately preceding
that Distribution Date, minus the sum of the liquidation proceeds for the
monthly periods which are the first, second and third calendar months preceding
the calendar month immediately preceding such Distribution Date, and the
denominator of which is the sum of the remaining gross balances of all
outstanding receivables as of the last day of each of the sixth, fifth and
fourth calendar months preceding the calendar month immediately preceding that
Distribution Date.


     The annualized loss (recovery) percentages reported at each Distribution
     Date are as follows:

      November    2003      0.6260%              May    2004           -0.1731%
      December    2003      0.2343%             June    2004            0.4704%
       January    2004      0.1015%             July    2004            0.4182%
      February    2004      0.0397%           August    2004            0.7442%
         March    2004     -0.2518%        September    2004           -0.1235%
         April    2004      0.0718%          October    2004           -0.4461%


At each Distribution Date a three-month rolling average delinquency percentage
is calculated. If this percentage exceeds 2.0%, any monthly excess servicing is
used to fund the reserve account to 10.0% of the ending receivable balance. When
the delinquency percentage falls below 2.0%, the reserve account requirement
returns to the greater of the specified target amount or the specified minimum
balance.

The delinquency percentage is calculated as follows:
The numerator of which is equal to the aggregate remaining gross balances of all
outstanding receivables which are 61 days or more past due as of the last day of
the related monthly period and the denominator of which is equal to the
aggregate remaining gross balances of all outstanding receivables on the last
day of such monthly period.


     The three month rolling averages reported at each Distribution Date are as
     follows:


      November    2003     0.46518%              May    2004           0.53340%
      December    2003     0.60757%             June    2004           0.54329%
       January    2004     0.62839%             July    2004           0.56742%
      February    2004     0.64127%           August    2004           0.56689%
         March    2004     0.53860%        September    2004           0.57135%
         April    2004     0.54079%          October    2004           0.53344%
