Taylor Camp

I live in CT and we have a camp in rural Maine which has no mailing/shipping address. All my purchases have been shipped to a friend who lives about 5 miles away. So we have different service, shipping & (Credit Card) billing addresses. The only address Starlink has is the shipping address which they presume is the service address Does this matter. I can only enter one address in to my account and currently it is the shipping address. Anyone have any suggestions?

We have a camp on Tunk Lake in Sullivan, Maine. We have a great skyline North, East & West, but not south. We have received our dish, but am not sure if having a obstructed view of the South is going to prevent us from having contiguous service. The App show the obstructions south, but it is not clear if there are enough satellites passing overhead at any given time to give us continuous service 100% of the time...or do you need a "perfect view of the sky" to get that. We rent the cabin when our family is not there and we want to eliminate HughesNet and DirecTV dishes, but don't want to do that if we don't get good and reliable Starlink service
