Unfortunately I couldn't locate where my problem is with the slide out without tearing out the whole section of coroplast. I'm just not as limber as I used to be, even with a mechanics creeper/crawler. I decided to have an RV shop find and fix the issue. I couldn't get an appointment before Sept. 24th so until then, I'm SOL.

I asked him to do one thing and he didn't do any of them.
