Class C overhead Cabin Leak

I started this thread last year and get my Rig pressure tested.After that I was still noting some water under the matterss in the overhead bunk.This year what I did different is that got my Rig parked in a position with front end at higher level than the back.So far I have not seen any water in the front overhead bunk bed area.We have lot of rain so far here in Maryland but no trace of any water.Does just changing the position of the Rig how parked did the trick or something else.Any comments/Suggestions.I have scheduled another pressure test later in September this year.
