Well after taking closer look at the slide, it appears the front side has dropped. Take a look at the pictures.
You can see on the far side, the rubber is touching the top, but on the near side it is about an inch above. The rubber seal looks like it is level across.
We called the dealership. They said they promised us a leak free, read to go camping trailer when we purchased. So they are having me bring it in on Wednesday to take a look.
I hope they get it fixed for free.. and I get it back before my next trip on the 25th
