I have a '93 Dutchmen travel trailer I bought used about 10 years ago. The guy I bought it from showed me a big box in the closet. He said "That's a folding tub door. I could never figure it out, so we just use a shower curtain." I've done the same for the last 10 years, but every time I open the closet I get the urge to put up the door. The box says Sterling Kinkead Folding Tub Door F325-36S. There is no manual or installation instructions inside the box, just the folding door, aluminum tracks, and a bag full of hardware. I've tried searching online for installation instructions, and even emailed the company, without success. Anyone know how this goes up, or have a link to the instructions?
