In my particular case, I have DN, with one 2 tuner receiver. It is counted as one receiver if I keep the phone line connected (no extra $5/mo multiple receiver charge)
If you were to register the subscription as "in an RV" or "I'm a trucker" I think you could move one receiver between multiple locations. Forget about multiple receivers being authorized on one account unless the bend the
rules for you (which I doubt).
Even being an "rv/trucker" would be your bending the facts a bit...
