The build went extremely well and both I and the wife are happy with the results:
Hardware and bungies from Creative Shelters.
Switched out the nuts that came with the conduit hangers with nyloc lock nuts:
7 cuts to the conduit, following the cut list provided on the Creative Shelter's website. Permanently mounted the top rail and middle rafter bracket:
Framework connected:
Tarp in place and awning up using the adjustable tent poles from Cabella's:
Finished awning:
It took about 15 minutes for two people to set up. This was the first time, so subsequent set ups will be quicker. Tear down took 10 minutes by myself. Strapping and unstrapping the tarp to the framing takes up the majority of the time.
We're both very happy. Very sturdy construction. Less than $225 in parts. Nothing was permanently altered on the trailer since we used the existing trim bolts. Poles stow under our futon out of the way and the connectors / bungies all fit into a small box.
