Been doing exactly the same for the last 15 years with either Directv or Dish network. I just purchase the same sat dish installed on our home online and set-up upon arrival to our destination. Not as important for SD viewing since only a single satellite is locked in, but for HD channels your satellite tripod/stand must be level/plumb to acquire the 3 satellites. Practice setting up your RV sat system at home first that way you could get the hang of it and work out any bugs in your RV wiring. Takes us 10 minutes tops and we have every channel we have at home while RVing.
