I posted the exact same issue about a year ago. Still haven't gotten the problem solved. I have spoken to several grey wolf owners. Seems the problem goes back to 2014. Mine is 2016 26dbh

I got tired of leaving the slide out. Easy fix. Removed seal and replaced it the way it should have been. Ran a bead of clear silicon across the top. Done. Wish I had done this 6 mos ago.
