Which Slides Work

JMO, but it's not a matter of IF a slide mechanism is going to fail but WHEN. Yeah, yeah, I know - lots of you say you've never had a slide issue but I've likewise talked to plenty of unhappy owners who have had slide problems. Our current trailer is the first one we've ever owned with a slide and although it's been fine for 3 yrs I always have that thought in my head that says "Is this going to be the time I push the slide button and nothing happens?" Can't say I want to find out. :W
