Hi. I have a new 2011 Big Country 3450TS. Just had a night of rain at Pismo Beach and I'm finding a small drip at the inner side of the Bedroom slide. I see that the weatherseals along the slide are not consistently even along the sides. i.e. partly turned outward and partly turned inward. Should the weatherseals be pointed outward all along the edge and along the top? Is there anything I can do to ensure that it is properly weathersealed when I open the slides?
