Item 1. Security and Issuer

This Amendment No. 10 to Schedule 13D on the Class B Common Stock of Rush Enterprises, Inc. (the “Issuer”) is being filed on behalf of the undersigned to amend the Schedule 13D, as amended  ( the “Schedule 13D” ), which was originally filed on December 12, 2008.  Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meanings as set forth in the Schedule 13D.

Item 2. Identity and Background

Item 2 to Schedule 13D is amended, in pertinent part, as follows:

              This statement is being filed by various entities which except for LICT Corporation (“LICT) and CIBL, Inc. (“CIBL”), engage in various aspects of the securities business, primarily as investment adviser to various institutional and individual clients, including registered investment companies and pension plans, and as general partner or the equivalent of various private investment partnerships or private funds and as a registered broker-dealer.  Certain of these entities may also make investments for their own accounts. Mario J. Gabelli (“Mario Gabelli”) is deemed to directly or indirectly control these entities through his ownership interest.

The foregoing persons in the aggregate often own beneficially more than 5% of a class of equity securities of a particular issuer.  Although several of the foregoing persons are treated as institutional investors for purposes of reporting their beneficial ownership on the short-form Schedule 13G, the holdings of those who do not qualify as institutional investors may exceed the 1% threshold presented for filing on Schedule 13G or implementation of their investment philosophy may from time to time require action which could be viewed as not completely passive.  In order to avoid any question as to whether their beneficial ownership is being reported on the proper form and in order to provide greater investment flexibility and administrative uniformity, these persons have decided to file their beneficial ownership reports on the more detailed Schedule 13D form rather than on the short-form Schedule 13G and thereby to provide more expansive disclosure than may be necessary.
