I have lightened my design plans. I have a house window in the basement that I used to fit a 5000 BTU AC into. My new plan is to mount the window on the drivers side and just mount the AC after I park when it is needed. This guys build in this video is the nuts and bolts of how I picture mine going together. I will just polish it up a bit and add a curved nose.
Also, his roof joists are to skinny and his walls are too thick (I assume). I plan on 3" joists and ripping 2x4s in half for 1.5" thick wall studs.

His back door design starts at 9:20 on the video
The question I have is this, I want a 5yo usable door in the back but I also want a wide entry into the trailer. I am thinking about using his door and frame design to build a double door setup. Is this the easiest backyard design?
The short version of the plan now is to have a bunk bed running sideways in the nose and having a queen size bed under it with our feet under the bunk bed.
