We have 3 TVs in our AS and one Direct TV box. We generally have to logon to the Direct TV site to "reenergize" the box if we haven't been out in a while. We have a Winegard Carryout and it works well. We tried the manual dish and sometimes could have it working in 5 minutes and sometimes more than an hour.
Recently purchased an Apple phone app "SATOOLZ DIRECT TV" It shows you the Direct TV satellites locations in the sky so it makes placing the dish much easier. Also easy to check a site before you settle in.
A little while back I was interested in installing the Winegard Traveler on the roof and talked to a professional installer. He advised against it, as HD would not appreciably improve the picture on the size of TVs in the trailer. He also mentioned the problem of line of site for satellite reception and the need to rewire the interior from RG cable to HDMI for HD to work.
