Schwintek slides

When Schwintek first came out 4 or 5 years ago, I thought they were junk. We had numerous problems with them on almost all the RV's that used them. Well after working on them and really understanding them, the problem is in the INSTALL and DESIGN by the OEM maker of the RV's. ALL the Schwintek does is move the room in and out on the side tracks. The Schwintek DOES NOT support or lift/hold the room. The ROLLERS do that and are designed and installed by the OEM. It just pushes it in and out. If the OEM designs the wall framing and chassis frames too weak or does not install the floor rollers correctly, then the system fails. If they do not adequately build a solid enough floor in the slide room(The OP's problem) and the rollers push thru or indent in the outer floor, the system fails.

Then why do some find shavings in their tracks, and why is the fix to add another set of rails? If all it's doing is pushing the slide out, it sure seems like it's still too small of a system to do that on larger slides. I'm no engineer but that reeks of "we need to band aid this system to handle what is asked of it".
