ATTACHMT: ATTACHED TO 3/2/95 LETTER FROM PHILIP R. RECHT TO JOHN E. GETZ (REDBOOK (2)); PART 571.7

TEXT: We are in the custom trailer manufacturing business. Most often we purchase new trailers and finish them, primarily inside, for specific applications such as medical trailers or trailers for specific electronic functions (see enclosed Brochure). In suc h cases our new trailer product is subject to all of the latest DOT regulations. However, in other cases we start with a used trailer and change its finishing and equipment for a new application. For example, we recently took an old (1985) vintage trai ler, stripped the inside, and refinished it for a major computer company to use as a mobile marketing facility. In this case the running gear did not change nor did the Vehicle Identification number. However, ownership did change which raised the questi on of "Newly Manufactured" as addressed in @ 571.7 "Applicability" (copy enclosed). Telephone discussions with Patrick Boyd and Ken Hardy in Vehicle Safety indicate preliminarily that this is not a newly manufactured trailer because the basic trailer st ructure did not change. However in some cases we may cut a hole in the side and install a door for a specific application.

What we are requesting is an interpretation as to whether we would fall in the category of a newly manufactured trailer if the running gear. VIN, and the basic trailer structure do not change, but the ownership does. In the example above we did add conspicuity treatment, not because it was thought to be legally required (although we did want to protect the company prior your interpretation), but mainly from a liability and safety standpoint in the event of an accident and subsequent litigation. If you have any questions regarding this request please call me at (513) 752-9000 ext. 208. Thanking you in advance. I am
