Siding bowed out on slide wall??

[my2boys]

On my slide out wall at the bottom, the siding seems to be bowed out. I opened the slide and crawled under and it appears there is a 2"X3" (couldn't see the wood i am guessing the size) that runs at the bottom. It looks like it starts at the corner and ends at the wheel well opening. I bought the trailer used so i don;t know what might have happened. It looks lke a design flaw as it is a fairly long distance and dosen't really look like it attaches well to the wheel well. Has anyone seen this or have any suggestions? Not sure if it may have rotted or just broken. Everywhere else i felt seemed solid (walls, floors etc) I have a couple trips planned in August so i am reluctant to pull the thing apart right now but i would like some ideas/tips for what i may be up against. I have attached pictures, not sure how to post them

HI My2boys

What you are looking at is Darco wrapped OSB board that creates the lower part of the slide below the floor. It is about ½” thick board and screwed to the sill plate.

Looks like this.




The board may be water logged and warped. If you look straight up from the bottom under the slide see if the board is attached firmly the entire length of the slide. It is only held on with wood screws about every 2 feet maybe a little more. If it has a large gap in the board attaching to the slide sill plate that lines up with the bow in the siding, I’m thinking some how the screws are loosened up

See this post it has tons of pics in and the issue I dealt with on my slide.

And while you are viewing that post, your slide is made like mine with a Darco wrapped bottom. There are screw holes in each end holding the floor up to the side walls. If you floor is solid and not mushy, now is the time to plug up those holes before water get’s in. If the floor is soggy in the area of the screws….. well follow my post…. and glad to help.

Hope this helps.
