I'm doing some research for my aunt and uncle who have a Fleetwood Bounder that is pre-wired for Satellite TV service, but haven't actually used it yet. They've been using the antenna for local channels, but they would like more options. I believe they just have to sign-up for a satellite TV service, but I'm not familiar with them to know what would be best for them as RVers. Can I get your feedback? Thanks!
