You can use an AB switch to make it easier to change configurations.
It appears that my information was out of date. While Dish does not officially support wireless Joey (client) receivers, apparently it will work. You have to use an adapter to connect them to your "home" wifi network. (In an RV, you would have to put in a router in order to have said network, or have some other means of creating a "hot spot".)
DirecTV has announced that you will be able to do this with Genie & clients soon, but it's not available yet.
