Karen, please don;t let some of these people drive you off. Many of us very much enjoy being challenged to come up with new ideas, many new people do show up here and many of them seriously need to gather info as they have no initial point of reference. While I am not an OTR Professional I have spent a considerable amount of time driving, everything from motorcycles to my current 40 footer. I , like many others here have seen things while driving that boggle the imagination. Rad a book? Newspaper? Shave? TV? Computer? certain bedroom acts? Yup seen it all. So asking a question is a good thing. Many times, I think it is genetic, I ask a question jut to get a conversation started or to make sure that all options are understood. You never know when a conversation like this one will bring to light something we'd never have thought of on our own. One simply needs to ignore some of the more 'personal' responses. Not everyone had learned to discuss things in a polite manner.
