I have read a lot of concerns about thick insulation limiting the height in the bus, and the roof raises to help out.
So here is an option and how i live in this Skoolie;
I didn't insulate because i didnt know if i would even like living in a bus, 2 years full time later... Now i know, however i did put down these soft foam puzzle floor pieces for kids areas. I live a bit Japaneese style in my bus; everything is down low. The foamy rug covered floor is soft on my knees. The only time i stand is to stretch.
I am planning bus 2.0 in my mind and plan to insulate the holy f$@& out of it. I survive winter with a nice homemade wood stove and buy wood by the pick up truck load, but i also sleep in a snow suit lol sooo yeah next bus will be more comfortable, but i do not plan to raose the roof and am going to lose about 8" to floor and ceiling Insulation, so Japaneese style seems a cozy fit for Pajamas kitty and I.
All my furniture sits below the bottom of the windows. I even cut the bottom 2 drawers off a dresser and off a book shelf. So it's low down in the streets style. Most my bus time is spent sitting on the couch, at the work bench, or laying in bed. When i want to walk upright like humans i exit the bus and put on my humanness.
Thought i would share this option because i havent read anyone suggest it here. I love figuring out how to work with what i have, and what i don't have. $
