Reciever in camper - DirecTV

I recently installed one of our HD Directv box in our camper. My question is how do I watch local channels on it whenever I'm out of my home viewing area. I would prefer to watch my home local channels but at least should be able to watch the local channels in whatever area the camper is in. Please advise how I can achieve this. Thank you in advance for viewing and addressing this issue Sincerely, Mitchell Rick
