Thanks for checking on it. It spent 90% of my time with it on a seasonal spot. We got it in May of 15. It left the campground three times and didn't go far. No large bumps or anything crazy in that time. I had it at home and then it's been at the dealer since early November. The tech said he thought it was stepping there too, but I just find it hard to see that happening. It's not a spot you can really step on, and we don't really use the camper with slides in at all. If I need to get in the kitchen with the slide in l go through the garage. It's wide open that way. So, I have no idea.
The tech said screws went in from above so that made sense. But if screws pulled through the wood, that would take some force for sure. The slide seemed to pivot funny going in and out, but I think that might be a result of, and not a cause of the separation. I ran my fingers under the wall and the screws were broken, actually. There was just a short stub under the aluminum.
Let's say it's not from any sort of impact or bounce, what else could cause it? I know sight unseen that's not easy to say. Like I said earlier my concern is other wall sides.
