2000 Gulfstream Innsbruck Slide needs to be replaced


Recently purchased a 2000 Gulfstream Innsbruck travel trailer. During cleanup and preparation for a camping trip, noticed water pouring thru the roof of the slide during a heavy rain. After a closer look, the slide is damaged beyond repair and needs to be replaced. The trailer trailer is not safe to travel due the slide currently separating. I called Gulfstream and they do not sell replacement slides.

Does anyone know of any online instructions for rebuilding a slide? I've watched Youtube videos but did not get specific details of the reconstruction.

Any suggestions or help is greatly appreciated.
