great quality, easy to put together, arrived early.  rain water beads up so water proof.  zippers very good, tie backs strong only area for improvement is from manufacturer all bolts and nuts should be packed in  plastic bag not paper with plastic cover, there  bag the paper ripped and bolts, nuts, washers everywhere in box, loose, so short 1 bolt and nut, no big deal, very happy, would recommend, heavy duty!!
