If I am reading your post right you have an RV account now and no residential account? If this is correct you need:
DirecTV compatible dish. The only automatic one I know of is the Winegard TRAV'LER. It is not a portable and must be mounted on your roof. Not good if you are camping in an area with trees. I use a Slimline Dish and a tripod from tv4rv.com. It is easy to set up and has served me well for over 5 years.
You will need a new DirecTV receiver. The Genie HR44 is what I have now. I use the coax that is already run to the front of my rig from the a/v area to get the signal to the front TV, but a wireless Genie Mini would work also.
My wiring is:
DirecTV Slimline dish connected to the sat in connector on the side of my rig. A broadcast TV ant input could be used, but you would have to make sure the signal booster was removed.
DirecTV Power inserter, SWM compatible signal splitter, Genie HR44, rear TV.
If you plan to use a wireless Genie Mini you wouldn't need the SWM splitter. If you will use the coax to the front TV then you would need the splitter and another receiver DVR or Genie Mini up front.
I would upgrade my RV account to the new Genie as described above and when in your new condo just move the Genie inside with a hard mounted dish. Otherwise you will have to have 2 accounts. I know people that have a residential account and take their home receiver with them in their RV. This is the reverse of that and you keep your DNS also.
