Voyager2000 and Cluemeister:
Thanks for your comments. I have really enjoyed working on this thread (I know - get a life!). I have enjoyed some type of RV for over 30 years, and felt it might be useful to share some of my experiences with a brand new unit. That you and others keep responding, plus all the viewings of the thread, seems to attest to some value in continuing. I hope you either contribute to the thread or start one of your own. In spite of its many shortcomings, I am still pretty happy with my choice, especially for the purpose I use it.
