I would say go for it, all except the Winegard Travler. Please DONT! I have had Travlers on my RV for probsbly 10 years. In that time I have had two failures that required I send the whole thing back to Winegard. Last one last fall cost me a thousand dollars to make it work again. All that for an antenna system that I have been able to use a hand full of times. Remember, putting a dish on the roof means you must have a chear line of site to the sats to get reception. So, unless your going to be sitting in the desert its a waste of money. For less than 300 dollars you can get a ground based system that will work 99.5% of the time.
