here is some of my travels
Here is the original idea for the interior. Note the fold down bunk.
I don't have any fab experience other than my van. I am learning as I go but seem to be pretty handy.
Eventually attached bunk to the roof.
Now I am redoing it again for possible short term living saving cash while building the bus. I am not yet sure I want to live without a bathroom and shower but would save thousands on rent.
