Same here and everywhere. The slides have become so tall inside that the angle is almost level. I don't worry about it as the little bit of sag still keeps the water away from the side of MH and the water will run off the end before it gets that deep. Be careful sticking something up there that you don't create a negative angle back towards where the slide is mounted to the side wall. Standing water gets bored and talks little seals and crevices into giving in. You don't weant that kind of party going on up there.
