We just picked up our 2012 ST25RB Feb 11th, and used it for the first time on our vacation to Florida. Between the sales demo when we picked it up, and couple of stop overnighters on route as well as setting up in Florida campground, slide out has worked flawlessly. I have seen you tube video's as well as actual manufacturers website video on how to disengage motors in event of failure....seems simple enough, but hopefully never have to do it myself. I will have to invest in a short ladder though just in case I need to reach up there to disengage both motors. Other forums I have read seem to suggest this slide out mechanism is one of the better ones. Sorry to hear you had a problem with yours. I'm always a little nervous when it comes time to "bring in" the slide. Last trailer we had (Citation) had no slide so that was never a concern. But after having the slide would never buy a trailerwithout! Wincrasher was right about the weird humming noises slide makes just seconds before it either extends or retracts, butslide does come in nice & evenly. Good luck in the future & happy trails!
