We had problems with both of the slides on our previous coach, a 33' Class A. Each time, it was a broken shear pin, which meant you couldn't crank the slide back in. They were too big to push.
It seems logical that since the bedroom slide on the 25.2 is much smaller and lighter, there should be much less strain on the mechanism. Lippert, the company behind Schwintek, has been making slide systems for many brands for many years.
One key reminder: don't reverse the slide without running it until it stops.
Only some of us learn by other people's mistakes, the rest have to be the other people!
