I think when you talk about RV's it just confusing what the poster wants. Very different and requires different documentation. Another thing, having locals from Dish has no bearing on getting them from AAD. To get distant markets you have to be in an area that does not get locals via an antenna. You can get a good idea by going to a site like Tvfool.com and see what you are predicted to get. It may not be the exact same results AAD gets when they input your address but it will be close.
If you can read between the lines......... Whatever address you give AAD will be the one they check. You can give them what your mailing address is separately. They have no connection to Dish other than broadcasting from their satellites.
