Not sure why all the hostility towards sliders.....:h If someone doesn't want one then dont get one. Isn't it that simple? And if you "need" one then it would only be because your short bed truck and trailer combination doesn't allow enough clearance to achieve the turning radius you need. I would think that most short bed trucks could only benefit from a slider, even if its never used. If you have a newer short bed friendly trailer then the likely hood of needing a slider would be slim. I use my slider a lot and I was told that I wouldnt need one too. After purchasing mine, Superglide had just introduced their less expensive and smaller 18k auto slide which fits on standard rails. I would have definitely gone that route instead of the manual slider.
