Traveling in rv

 I have just gotten Diecctv because they carry MLB. However if the red sox don't make the playoffs I won't need it.

 I will be traveling in my rv the rest of the season and was assured by the sales rep that I would be able to get my local channels even if I left the area.

 He said the reciever does not care where it is as long as the zip code is not changed on my account.

 Is this right.  We need to get NESN on the road,. Otherwise I need to get MLB pac.
