Welcome to the world's teardrop playland. Enjoy the research. It sounds like you are planning more than one build, let us look at some of your drawings, rough is okay, we don't care. Eventually you will gleen lots of ideas from many trailers, what you put together will satisfy your needs,
We look forward to your questions. You will get opinions on both side of the argument here, take them both and do what you want.
Get the bathroom done, while you are doing it,you will have time to think about the trailer
