I leave 1 piece of PVC, with corners glued on attached to the trailer with 'U' shaped pipe holders. My side pieces are PVC With corners & T's (for leg attachment), the whole thing breaks down into 5 pieces that I store in my trailer.
The curtains are shower curtains shortened to 58" and attached with shower curtain hooks. It is approx. 4' X 3'. The upright PVC is an umbrella holder. More pic's in my album.
