We have a Schwintek slide in our FunFinder. The mechanism has worked without incident for almost 10 years. I wouldn't describe our slide as a "superslide" though. It has a sofa in it so it is probably a little over 6' total length. We did have one issue with it that I was able to resolve myself: Under the slide are three rollers attached to the main frame of the trailer. The slide rides in and out over these rollers. One of mine was impacted with caulk during the manufacturing process, and so, did not rotate. As a result the slide skidded in and out over this immovable roller. The accumulating damage went un-noticed for a time because it was all under the trailer. When I finally discovered it there was some damage to the floor of the slide. I managed to free up the roller and repair the floor and have had no problem since.
