I'm going to echo what others have said, give Sean at ProPride a call, absolutely out of this world customer service. If however you wish to seek a second opinion, give Andy at Inland RV a call, it is my understanding that he tends to favor Reese Dual Cams. Plus Andy's safety background is unbeatable where Airstreams are concerned. Though you might consider PMing Andy, I've never had any luck actually getting him on the phone when I call Inland, but have been able to reach him on the forums.
