One of the first things I did when we purchased our used 2002 Classic w/slide in 2010, was to have a Winguard bubble antenae and a solar panel. It costs $5 a month when we are using the Direct TV in addition to our home set up. The only down side is we don't get HD channels or local channels if we are out of our area. I have a separate antenna if I really need it. Mostly I watch Fox News and the Weather channel. I have never had a problem. By the time I finish hooking up, all my channels are operating. I tried the remote version and got really frustrated trying to get a signal at 11pm on a rainey night and decided right then that a roof mounted, automatic version was the only way to go.
