I have a 2013 Aliner Scout and love it. I spent July 4, 2014 in Falmouth, Mass. during a Tropical Storm that came through (probably 50-60 mph gusts and had NO problems.
I'm considering moving on to the Expedition with dormers. I've heard only a few reports about the dormers leaking (usually second-and) but I don't know if it's related to them being opened or closed. Would like to get some more info on the circumstances under which they leak.
