You have a misconception of what the Schwintek does. It DOES NOT support the room at all. The room glides on rollers under the Slide out floor. All the Schwintek mechanism does is move the room out and in. Now, is the Room to heavy for the Schwintek Mechanism to reliably move the room in and out? Yes, I believe the room is too heavy(because it is a full slide room). Now, that is a Winnebago fault because Winne designs those rooms and all Schwintek does is supply the mechanism to move in and out. A lot of OEM's dropped this Scwintek mechanism for full wall slides years ago. Because of the same problem you are experiancing. These problem almost always came up during the warranty period. You need to have paper or e mail contac with Winne about this issue and look on the various Winne RV forums to see what people with your design came up with and maybe Winne replaced the system for those people with another system. AS to your problems, replacing a defective Schwintek is NOT for Service centers and their Techs who do NOT understand the parameters of diag and replacing. There may be issues with HOW the original system was installed and if the replacements were installed exactly where the old flange sides were installed, all that does is continue the original install fault. Which occurs years or miles down the road. You need this RV evaluated by a Service Center that states they KNOW how to diagnois and replace/repair Schwintek in wall systems. I HATED Schwintek when this system came out more than 10 years ago. But after over 10 years of dealing with the system I finally realized that except for bad motors or a possible controller, MOST problems are caused by the OEM and their install. A in wall Schwintek when the system is detached from the outside mount flanges, you (well 2 or 3 if full wall) easily roll the room in and out on the bottom floor rollers. Doug
