I too had fears about slide when they first came out. In fact, I was so unsure that my first unit with a slide was a Dutchman unit with a manual slide. Crank it in and out... which got old in a few years but was issue free. Since I have had a couple of units with 1-3 slides and have had minimal issue. Like with most things, if the unit is level and stable you will never have a problem. They do require some lubrication and you should ensure they are clean before bringing them in, but that's about it. Not that it's my opinion but in conversation with a sales manager of a large dealership in my area a couple of months ago he told me that units with no or only one slide set on the lot until someone comes looking for that exact item or a discounted deal. Even trade ins with 2 or more slides jump off the lot in comparison he says.
