while rv'ing - DirecTV

while rv'ing how to receive local channels through winegard traveler sat antenna ? DirectTV, when not owned by AT&T, was able to just change the base address to wherever you were, and all worked fine. Change back when returning home. My last 2 1/2 months with AT&T DirectTV have been nightmare. On hold, switching from customer svc to tech support. First two times, all worked okay. Last three trips, no one knows what to do ? Did something change with the system ?

This question, "while rv'ing," is about DirecTV channels, programming, equipment, and sports.
