We have been with Dish for years but are thinking of switching to Directv. Seems everyone we know have. I have a couple of questions. If we were to get the Genie system could we get an additional regular reciever. We have a camper that we take up north. They have a Directv dish and we would be able to connect to it. We would be looking at getting the Genie system on 3 TVs and then a regular receiver for the 4th TV to move between the house and camper. Is this possible?
