         Re:      Thor Industries, Inc. - Registration Statement on Form S-3


Ladies and Gentlemen:

        We  have  acted  as  counsel  to  Thor  Industries,   Inc.,  a  Delaware
corporation (the "Company"), in connection with the registration,  pursuant to a
registration statement on Form S-3 (the "Registration Statement") filed with the
Securities and Exchange  Commission under the Securities Act of 1933, as amended
(the "Act"), of the offering and sale by the selling  stockholders listed in the
Registration Statement (the "Selling Stockholders") of up to 952,784 shares (the
"Shares") of the  Company's  common  stock,  par value $0.10 per share  ("Common
Stock").  The Shares  were  issued by the  Company to the  Selling  Stockholders
pursuant to the Agreement  and Plan of Merger,  dated as of November 9, 2001, by
and among the Company,  Thor Acquisition Corp.,  Keystone RV Company and certain
former securityholders of Keystone RV Company named therein.

        We have examined originals or certified copies of such corporate records
of the Company and other certificates and documents of officials of the Company,
public  officials and others as we have deemed  appropriate for purposes of this
letter.  We have assumed the genuineness of all signatures,  the authenticity of
all  documents  submitted to us as  originals  and the  conformity  to authentic
original  documents of all copies  submitted to us as conformed and certified or
reproduced copies.

        Based upon the  foregoing  and subject to the  assumptions,  exceptions,
qualifications  and  limitations  set forth  hereinafter,  we are of the opinion
that, when sold and delivered as described in the  Registration  Statement,  the
Shares will be duly authorized, validly issued, fully paid and non-assessable.
