We have the Itasca version 40AD. I can tell you I've had both problems the main slide leaking and the vinyl falling down because of the heat deteriorating the foam.
As to the slide (drivers side) I got up one morning after a very bad storm, lots of wind and tons of rain. The galley was flooded to the point my iPhone was on the kitchen counter and was destroyed by the water. The vinyl was bulged and when I touched it it came down with like another gallon of water.
Once we got home, I took the slide topper off and ran a strip of EternaBond tape along the seams. This seems to have stopped the leaks.
Like your MH ours sat in the Florida sun for most of its life and I believe that was the cause of the vinyl pulling off the ceiling. For this you need to remove, clean and reapply. I posted a couple pictures here:
Hope this helps.
