Great! Just as described. Got this for our new travel trailer and does a good job protecting the roof

It was a little work to put together,I'm hoping it will hold up to our Michigan winters. Also they should let us know to remove the plastic from the roofing. We found it when it was half finished.

first its not truly 20 x 40 . 19 x 39 is more accurate. Second it comes all packed very well on one pallet . However that should tell you something about the construction. This is in a few hundred pieces that are all screwed together using the best chinese self tapping screws. I absolutelty would not install this on anything but a solid level surface. The roof panels are 18" x 60" and have to be screwed in one panel at a time. If i had to do this over again I would definitely go another route. There is not a good plan for laying out measurements . I had to derive that from assembling a complete section then i was able to lay it out on my site. Overall it is a shelter and it may last but i highly question the snowload and wind ratings given on this. Also dont even attempt to put this together if you are not very confident in your ability to interperit very vague drawings and use a number of power tools.

Please change your cover picture to a picture of what you are actually selling to people. It SHOWS 2 X 3 but I ended up with 1.8" tubing. Not worth the Price for that size plus BIG stability difference
