I called DTV back and got my local channels changed to here in Texas. Apparently you have to use the correct terminology. All I said was "I would like to change my residence address" and she was more than happy to do that. Didn't mention "local channels", "RV" or try any explanation about where I was or where I used to be. So I see this thread as complete and I want to thank everyone who participated and tolerated my many questions.
Thank you for your time.
