Just about everything that moves requires some kind of lube sooner or later. Problem is most get overly ambitious and lube too often and then use the wrong type of lube. Play it safe, if you don't have any problems don't create one. Use the OEM recommendations in your manual (or call) for type of lube, usually a Teflon spray or something that won't drag gear lube onto your carpet. Keep the outer sides of your slides waxed liked the rest of the rig. Helps them to go past the rubber seals easier. Use the rubber seal conditioner sold at CW or the like on the rubber seals about once per year. One $10 can should last a lifetime! Keeps them from drying out and allows the slide to go by them easier. This is what keeps the wind and rain out so you want them to be somewhat pliable. When the rubber seals dry out and start to stick they tear when the slide is extended so you can tell if they are getting dry by feeling them. No magic, just like everything, do it in moderation and have fun!
