Yes, the original problem which occurred on the front edge of the slide out (closest to the front end of the trailer) has held. Unfortunately later developed the same problem on the back edge of the slide out. Initially I tried to fix by removing the three bottom-most screws which were coming loose and filling in the holes with toothpicks and re-seating. This did not hold, so I replaced the screws this time with 1 1/2" size 12 screws. On the front edge I used 1 1/2" size 10 which as continued to hold. The original screws placed by Winnebago are size 10 yet only 1 1/4" long and self- threading. We continue to have intermittent problems with the slide out refusing to open when we arrive at a new destination and set up. So far, thankfully, we haven't had a problem with them closing. We have taken to being really scrupulous with leveling in both dimensions and in cleaning and drying the upper and lower slides every time we are going to close the slide out to break camp. Still having some intermittent issues, though. What a mess these Schwintek systems are!
