I'm the opposite of most. Have Dish for the coach but when home and the service is active (we're month to month on the subscription) the receiver moves into the house and I'll use the antenna on the coach since where the coach is parked is about the only place in the yard with a clear line of sight to the satellites. Subscription cost about $50 a month for the package I selected.
While on the road we use our cell service for most of our internet usage. We don't stream entertainment from the phones to save on bandwidth usage. CG internet can be a bit slow but works well for general use but I don't normally depend on it for streaming purposes. Between the Dish subscription and DVDs we don't really need to stream to the coach TV.
