Tinia, here are the pictures of the hooks attached to the lip of the roof. I hope this helps. The awning only took a couple of hours to make. If you need more info please let me know
This shows the large washer I used to attach the hook on the inside of the lip
This is an outside picture of the hook
Another picture of the hook
I rounded the door corner so it could not damage the tarp, if the tarp came in contact with the door
I use 5 poles to hold up the tarp. The only thing I would do different is make the tarp over the back door about 7' out from the trailer.
Let me know how you do
