You trailer guys may be interested in this. Tom, from Gilbert (Phoenix, AZ) is the owner / builder. Tom was a heating/ refrigeration tech and said this was a pretty easy build if you have the tools (and experience if I may add).
This trailer weighs 1300 lbs and is pulled by his Tacoma. It used to weigh more but he downgraded the luxuries. It is very comfortable looking. The awning takes 5 minutes to setup and stays put in 50mph winds. The windoors were obtained from A.R.E.. Tires are 15".
Here's the pics - all 6 of them.
