Let me play devil's advocate for just one post (imagine THAT). Chopper, you chose this ultralite RV for a reason. What exactly would you use for a roof if you were magically put in charge of design and production? Keep in mind that it can't cost more, it can't weigh more and installation must take no more time.....
And Bisjoe, "The dealer sales people will often give information that is questionable, if not wrong" I just can't believe you'd say something like this.
