Hi Will. The trailer has well over 20K miles on it since I built it. No issues at all. All my trailers have a tongue box to hold all the dirty stuff. So I needed to add the angle iron to support it and beef up the tongue at the same time. I did need to add 1" wheel spacers to get the tire out far enough to be able to cover the frame with wood. I don't like seeing the frame.
I have never weighed the trailer, My guess is between 800-1000 lbs. I hope to weigh it before I sell it.
There is no material list. I used 1" soft Maple for all the frame work. Cabinet shelves and sliding headboard doors were 1/4" Birch plywood. The cabinet storage doors are 1/2" Baltic Birch. The roof was 2 layers of 1/8th" Baltic birch with the joints staggered. Roof spars were soft maple to I believe. The skin is mahogany that had a Birch back which worked out well.
Windows and door latches and the galley props and lock came from
http://www.teardroptrailerparts.com/Hinges were from
http://www.marinepartdepot.com/ Lots of the smaller stuff I found on Ebay. Fenders came from Farm N Fleet, they are common fenders sold in most farm/trailer related places.


Here is my current build. While it is different, it might offer a few suggestions for you.
