Be sure when you are purchasing SAT equipment for the RV, that you take into consideration that SD (standard definition) service for Directv will likely be stopped sometime around the end of 2019. That is why we went ahead and upgraded our in-motion SD dome to HD (High Definition) service from Directv with the roof mounted Winegard Trav'ler. It was expensive but works well for us. We still have an SD portable sat dish that we can use when we are parked under trees blocking the roof-mounted Trav'ler.
