To Paul 0138,
Check your drain pan also. It is supposed to catch any water coming down the lip seals and any water flowing along the gear racks toward the camper. It then directs it out, theoretically. Mine is cracked. I was able to get a part number from thor easily. I also had the same problem with the slide trim. It was actually flowing down the outside wall, behind the trim, and into the layers of slide floor. I removed the bottom piece, cleaned everything, dried it out, applied eternabond to the corner, laid a bead of non leveling sealant onto the inside angle of the trim, reinstalled with stainless #10 screws, and recaulked the side and bottom pieces with proflex rv clear. Make sure to seal the mitered corners, they aren't perfect. Then I used 3m tape to reattach the corner plastic trim. Btw, some of the screw heads had rotted off with the body still left so I had to drill additional holes for screws. Some of the existing holes required larger #12 screws because they stripped. You want this piece as sturdy as possible. Then I caulked the vertical outer wall seams, the ones on the side walls, and the tops of the racks. Soapy water on your fingertip for caulking works wonders. I now received the tray from CW and will install that. I did this to my bedroom slide and my dinette slide. Dinette slide is dry but bedroom slide still has water weeping from a screw on the bottom. I even removed the awning topper bracket screws, resealed, and replaced with stainless. Still weeps, just like I fo when I see water on the floor. Btw, this is a 2017.
