Bedroom slideout leaking.

[morscuba]

Since I've had the MS, when traveling (slideout in) I have had a leak that runs down the slideout and makes a fairly good size puddle on the floor. When hooked up and running front has about a + 1 to 2 degree up angle. Last night parked (slideout out) front was at about a -2 to 3 degree angle down. Good hard rain and it looks like someone turned on the hose and let it run. Carpet on just the slideout is soaked. The wall does not appear to be wet by look or touch. I got up there and the seals (APPEAR) to be in place and sealing. Was wondering if anyone else has had that problem and what they did to correct it. I do know that had I been level it wouldn't have been as bad but nothing I could do about it last night.
Thanks for any input.
