I am looking into this as well.
This is from the direct tv web site:
"Distant Network Service (DNS) enables you to receive ABC, CBS, FOX and NBC channels from New York or Los Angeles. It's a great solution for travelers who want to enjoy these channels on the road in their mobile vehicle. If your main residence is qualified to receive Los Angeles/New York stations, you can also receive them in your RV, car or boat. If your main residence doesn't qualify for DNS, you may submit qualifying paperwork to obtain DNS channels"
