The only thing I can imagine to improve would be a full wrap around in fiberglass, top, bottom, sides, and under, with gel coat to give it color, that way it is absolutely waterproof, no worries about dry rot or leaks, and scarfing fiberglass and repair is way easier to do than to repair aluminum skins, my next build is going to go that way, it looks good, and maintenance is severely diminished, I am starting a standy similar to the puffin, only 6x10 with a Australian style sliding kitchen, and portapotty/shower cabinet, I wish I knew how to work CAD better to make blueprints, right now I have it all in my head.
This galley style is from a trailer called the "conqueror" from Australia, I really like it.
