Slide out bottom lose

[clr]

I have a 2015 Prime Time Sanibel 3601 5th wheel. After this weekends camping I noticed that the bottom of the main slide out bulged out about a 1/2 inch in the area of the wheel wells. If you push in on the outside wall of the slide out the bottom will move about a 1/2 inch. This is in the area with the arrow in the attached picture. I am thinking that this will only get worse with time as the tires throw up water from the road. Am trying to come up with a method to pull this tight and then seal up the bottom so that water will not wick up into the wall. Anyone have this problem? Or willing to offer a repair method.

I fought this same exact type of 'ripple' on my current RV. It was fixed on one side by warranty. The other side started doing it after warranty and was fixed by insurance when a flat tire destroyed the original sheet metal.

You can try more screws, more sealer, it will always come back.

The only way it was fixed was to remove the entire piece of sheet metal and reattach starting at one end. That way the bubble of pressure is removed.

Good luck!

I just discovered this the other day after our 5500km trip. On our 2701, there were only 4 screws holding the bottom on, one which never reached the wall. The other 3 were corroded and broken. I'm pretty sure I can run new (and more) screws under the outside vinyl trim.
