The schwintek slide units had a lot of issues a few years back. They were under engineered for the task and the solution was to add a third rail (2 at the top and one at the bottom). I know friends that had a THOR with this type of slide and had nothing but problems and a horrible time getting Thor to warranty it. Now you see a lot of these 2 rail units for sale. I haven't read of any issues since the 3rd rail was added to the Schwintek system, but personally I wouldn't buy an RV with it.
Your analysis is wrong on Schwintek slides. It IS correct as it relates to certain Thor products(3 rail). But, your statement that Schwinteks were not designed/engineered for the task is wrong. ALL the original designed and still used today 2 rail Schwinteks do is move the room in and out. They support NO LOAD of the room at all and are not designed to. The support of the room is done by the Floor rollers. The original Schwinteks got a bad rap because the OEM's designed inadequate frames and inadequate wall support when the hole for the room is cut out. After a few years of problems that had nothing to do with Schwintek, the OEM's beefed up their frames and in wall stud supports. Failure of a Schwintek now is usually related to bad wire routing(wires pinched and cut) or inadequate install by the OEM. Motors rarely fail. Doug
