I have not lubed them. They look ok from what I can see. I noticed a few tiny holes on the slide topper. Not sure if they're big enough that all of the water could have gotten in though them, but either way water got on top of the slide and worked its way in through the seals. I'm parked at a tiny bit of an angle. The auto leveler says it's perfect, by it's just barely leaning to the passenger side. The slide that leaked was on the drivers side angle brought the water in. Granted it was a pretty good storm....
The amount of water on the floor that came in around the bottom corner of the slide is especially concerning. I'm going to pull the slide in to tonight and try to take a look for any obvious signs of leaks. I just really don't want any water damage. :(
