Bending of outside wall when slides are out

**Hanebampel** · 09-07-2022, 08:40 PM

We have 2 slides (one in the living room & one in the middle bunk room) on the driver side. When moving these 2 slide out, I can see a gap between the outside wall and inside wall between living room and middle bunk room (see attached picture). When the slides are in, the gap is closed.
It seems that the large middle bunk room slide is bending the outside wall. Looking inside the gap, I can see at least 2 broken screws.
My questions:
- How critical is the outside wall bending?
- Should I add new and more screws to better connect the outside wall with the inside wall?

Thanks you any input

My initial thought is that the slide stops are set incorrectly, allowing the slide to move too far to the outside. How much force does it take to close the gap between the two walls manually?

I looks like the gap is getting larger as the slide (mainly the deep bunk room slide) is moving out.
How can I adjust how far the slide is moving out? It’s a Schwintek slide that stops “automatically”.

Because we didn’t try to close the gap, I don’t know the force, but I can easily check in the next days.
It looks like the inside wall is supposed to stabilize the outside wall by connecting both walls with screws (just an assumption based on the picture).

You are still under structural warranty. If it were my trailer I would schedule a dealer visit to be sure no welds are broken.

A Schwintek slide does make it more complicated. You probably need to have it checked out with someone familiar with that type of slide. I've never read about anyone adjusting a Schwintek.

I agree with others and your slide stops were not properly set or walked (they can, and do). Because the through-frame slide motors are high torque, they can very easily break things... Your coach should be inspected for broken welds in the portal frame.

Did you ever figure out the issue? My 2020 is doing the same.

Call GD. I believe this is a common issue with 31MB's and they are aware of it. If it is that problem it requires taking the panel off inside the bunk room and relocating and putting in slightly longer screws as many did not hit the material there for the bolts. It's a schwintek slide so no slide stops other than the flanges around the outside and inside. When the slide is pulled in the outside flange pulls the gap closed.
