This is the forward part of the slide. Same seal at the bottom.
See this is how I pulled the seal (rear) away and you can see water actually pouring if you look at my hand where the white water hoses are.
And this is the front seal releasing its water ...
Forest River has a long way to go for Quality control !
I wish we could come together at this forum and somehow attract their attention to these very serious problems their customers are facing.
I hope this helps and I pray to God you have no leaks. I do not know fo a fix yet Water in my opinion is travelling through those white rails from outside when the slide is out.
Hopefully the dealer I will take my traielr will be able to fix it.
