We switch our Directv account to Phoenix locals in the winter and back to Washington in the summer. Directv allows two switches per year with no push back.
We were in Arizona for the winter when I decided to go HD in the trailer. Directv came to the park and installed the Slimline SWM and HDDVR, along with a HDRec.
I also find my Slimline dish very easy to align. The mount has scales built into it. Set the TV to sat meter and just swing it on 101 and then fine tune on 103. Last time in Arizona I set it up and pointed to were I thought it was in the years before, AND was spot on!!! Ha! Ha! That will not happen that often.
