As the title says, I've had some rain water leaks into the trailer, and I had the ceiling support for the bathroom door fall loose. I also found virtually no caulk was under the metal shower threshold, which left a nice path for shower water to go under and leave a small puddle on the bathroom floor. I isolated the three water leaks from outside. The passenger side fender allowed water to leak in under the kitchen cabinets, and both of the basement pass through doors leaked. All were found while I was in the mountains in Sept (just what I wanted to do while archery hunting elk!). I stopped the leaking fender with gorilla tape run over top of where the fender meets the side of the camper, and the dealer fixed that problem properly during the next visit for repairs.
Unfortunately, they were also supposed to fix both leaks on the pass through doors, but they didn't! I found this quite luckily before heading back up into the mountains in Nov. I found the leaks days before I was to leave. So, I isolated and fixed them. On the driver's side I was able to make a long term fix because the problem was a lazy application of caulk over the screw heads that are on the inside of the frame. The culprit was the rear bottom screw head. The mgr's caulk applier just squeezed some caulk on the head and swiped it in one direction, which didn't seal the head on the trailing edge of his swipe. I removed all caulk from all screw heads on both basement doors and properly applied some good quality caulk that has wide operating temps. The passenger side door had a leak at the front and rear of it. The front was also a leak past a screw head that I fixed. But, the rear leak ended up being some kind of failure during installation whereas not enough caulk was put between the top edge of the door frame and the side of the trailer. Water got past that junction, came to rest on the top of the door's frame, and then ran down the metal frame until it go to the floor.....where it leaked out into the basement.
I shared this with the dealer before I left on my trip, and now I am waiting for him to call me back after emailing him pictures of how their tech only did half the repair on the sliding bathroom door that fell down loose on my elk trip. He made it more solid, but the ceiling slide structure is still installed crooked.
Here's some pics that I'm sharing for anyone else who has one of these problems pop up. So far, I'm fixing as much as the dealer is fixing. I give them a chance, and then I work on it myself. I don't know if they will fix the passenger side basement door leak under warranty or not since Winnebago only warranty's caulk for 3 months (a joke), but this seems to be a clear failure during installation and not a simple caulk failure. It appears to me that they didn't put a continuous seal of caulk between the door frame and side of the trailer before sliding the door & frame into place.
Two pics of how the water leaked past the outside fender molding and onto the top of the metal fender under the sink & stove. You won't see this unless you are looking for it. I stumbled onto it when I removed the drawer under the stove for another reason. You can see the white residue on the metal in the pic, which proves this leak has been happening probably since I bought it.
Pics of a properly sealed screw head followed by a pic of the mgr's lazy squirt and swipe caulking. Then the 3rd pic is one example of how the water leaked into the basement and ran across the floor.
A pic of the Gorilla tape fix over the passenger side door, and then if you zoom in on the pic of my brother under the moon, you can make out the same Gorilla tape fix over the fender's molding. I keep a roll of the Gorilla tape in my truck, and recommend it (not duct tape) for just these kind of emergencies.
The terrible repair on the bathroom sliding door rails. Sorry the 2nd pic is sideways.
