Once you have stripped the seats out, you have an absolutely blank slate. Most people put the bedroom in the back, the kitchen/bath in the middle and the living room up front. There are no set plans available simply because people play it by ear.
Hi, I'm new to the skoolie life. I'm looking for existing designs/plans that I can purchase and start my DIY. I would want plumbing, electrical, and everything else.
I made a list of all the things I had to have and all the things I wanted.. measured my bus out and took grid paper... 1 box equals 1ft and drew it out using household items and online for dimensions for things like twin mattresses. Worked well and fit most things into my grid. Plumbing and electrical schematics exist on the forums and others and in bulk. Good luck!
