I have had DirecTV for years. They are a little harder to work with when traveling. Generally they are OK with two address changes per year. Dish by all reports allows more changes.
By contract all equipment on an account is suppose to be on the same antenna.
One year while in Arizona, they insisted on taking the SB equipment out of service while we were in the RV in Arizona. Normally we just leave it on the Account to simplify things. I have found a chat session an easy way to switch locations.
I have Wholehome DVR setup on my own routers in both the SB and RV. Trailer has 2 HDDVRs and we take a HD Receiver from SB for the belly TV. Chris
