2007 Monaco LaPalma 34PDD. There were major leaks on the bottom corners of the living room slide when we bought it. We replaced all of the exterior seals but it seems to be missing some type of seal at the bottom corners. There is nothing to seal out the wind or water. I can see into the coach from the outside there is a large gap. This slide is totally different from the bedroom slide. One Pic is to show which corner. One shows from the outside looking in through the hole and the other is from the inside looking out through the hole. Any ideas as to what type of seal should be there?
