I'll post pictures soon (waiting on my new phone to come in the mail), but I'm trying to pin down a plan for converting my 1988 40-foot Bluebird school bus into my new tiny home. The seats have already been pulled out and the previous owners have put down a hardwood floor. However, one of my first plans of attack are to pull up the floor and insulate the dickens out of the bottom. I don't know that they insulated the floor at all. They did put up plywood boards along the walls beneath the windows and filled the spaces with wool and carpet foam, but I'm going to rip that out too because a lot of that insulation looks like nesting material to me, and I want to be the only pest on the bus, thanks.
My main concern right now is in putting in a new floor with insulation - how able am I to add stuff later, like a grey water collection tank under the bus with tubes draining into it (through the floor), or wiring, or other....stuff? I feel like I need to have every detail of the bus planned out NOW and lay the floor around what I want to do later, or do I install a whole solar power system now, and do the flooring later? Do I need to install a water heater now before I have water, or after?
I feel so overwhelmed right now - I don't know where to begin. I've started by making a small to-scale replica out of paper so I can play with what-goes-where, but I just don't know where to begin. I don't want to make a mistake by putting down a floor and getting it all nice, and then have to rip it up again later.
So, wise ones, where do I begin?
