This language you've been using was not in TheTaxBook excerpts I copied. Is it coming from a specific code or reg? Maybe NATP knows, but I don't.

A 2nd camera lens is not integral or life-extending or needed for operation of a camera, but it is still listed property. A second monitor screen is not integral or life-extending or needed for operation of a computer, but it's still listed property if the computer is. So why would a truck cap be different, if the truck is listed property?
