YES and no: IF you drive very far you loose network programming (ABC, CBS, NBC and so on).
Get DirecTV for your RV (Can be DirecTV or DirecHDTV but read my next post) file the RV waiver, ask for maximum number of receivers (NOT A GENI) and get a disaster recovery kit or two.. install your own dish at home and wire it up.
Now you have Network TV wherever your roam (Ok you can use a Geni, and take it with you, did not think of that) Read the next post on Antennas.
NOTE: Dish is not allowed to offer Distant Network Service and where as they used to have a 3rd party provider, they lost them as well.
