We have a schwintek slide on our 2012 FunFinder purchased spring of 2011. It's the first year Cruiser rv used this type. Ours has been trouble free and reliable. I especially like that it is flush to the camper's floor. There is no step up into the slide.
We did have one issue, but it had nothing to do with the slide's design. It was an assembly issue. There are rollers attached to the trailer's frame that support the slide as it moves in and out. One roller had been siezed with caulk and would not turn so it skidded along the bottom of the slide as it moved. Eventually this began to tear up the floor of the slide. I was able to free up the roller and reinforce the floor and have had no problems since. If you do have this slide, you should extend it and inspect the underside of the floor and the rollers to ensure you don't have a similar problem.
