I just found this thread and read the whole thing in one sitting. I too have a 2 door jeep and was looking to build a tiny trailer for camping. I was looking at building one similar to yours only squared front and back with a 1" arch on the roof. Squared to increase storage space inside and no galley hatch.
I had to look at your jeep twice because it looked almost like my 2010 I had. I now have a 2015 in firecracker red.
I really like your trailer build and your workmanship is very impressive! I have 40 years in construction and am retired now. I am always building or fabing something. I thought this would be a great project. My wife is retiring in 1.5 years and we are planning a month long trip to Alaska in the jeep for her retirement party....LOL. We still tent camp now, but she said no tent camping where there are bears! So I am looking to build this for our big trip and with it being so far out I will have the time. I am too old to try and work that many hours at a time.
Anyway I just wanted to say thanks for the pictures and the write up on your build. You have a camper to be proud of! I really like your idea for corner molding too.
