Coach with no slide outs

Just a question.. We've had 5 units (1 TT, 2 Class Cs, 2 Class As) over the years with slides and have never had a leak. I've always made it a point to keep the top/bottom/sides of the slide unit clean and regularly use silicone spray to lubricate the gaskets (making sure to clean them off on a regular basis, too). That, along with making sure the rollers under the slide were kept lubricated always kept them working like new and watertight. Having lived in Florida most of my life I have driven/pulled them through some serious rain without issue. We now have a Winne with the seemingly tiny Lippert slide system. I'm following their maintenance procedure and after a year, so far so good. Do most agree that slides need an extra amount of effort to keep working/dry and that paying attention to that rule makes problems unlikely? Over the years there have been a few times where I've heard someone's slide extending or retracting noisily and have wandered over to point out to the owner that a bottom roller was seized up or the slide sides were filthy and/or gaskets were covered with dirt and dry. I really suspect that owners who are not sufficiently aware on what's needed to keep slides working right are the cause of most trouble.
