I have been struck hard by slide water leakage on my Trail-Lite 211S. Somehow water is getting into the slide and collecting on the carpeted slide floor under the jackknife couch, soaking the carpet and the fabric valence that hangs below the couch. The metal pan under the slide floor itself seems dry. The wall surfaces of the slide are dry, only a small dribble of water coming from the lower right of the window to the floor. The top and sides of the slide look well caulked expept for the diagonal corner seams of the outside slide wall, which have a 1/16-1/8" gap and have never been caulked. Somehow water is getting inside the slide walls and pooling out at the bottom. Also, the top and bottom of the slide are tipped slightly in when the slide is out(unit itself is level to even low on the slide side) so water does not tend to run off but rather in. Then when the slide is pulled in the top squeezee wipers push the water over the sides of the slide and onto the inside floor of the unit. I still need to use a sponge to mop up lots of remaining water on the slide top.

We're in to the dealer this next week for repairs, wish them and us well. This should not be happening.
