Just thought I would add to the conversation. Got the idea to convert my Prius into a tiny home. Actually lived in it for a while in 2019-2020. Split time between parents, GF, and traveling. I think 50 nights out of a 400 day stretch. Then during covid I took it out west and visited some national parks. I wanted my build to be something that could easily convert back to the normal setup so no major installation. I used a mattress topper and folded it in half. Glued magnets on the top and used black felt to create a curtain and tinted the windows. All black inside. It was quite comfy. Here are some pics of my 2008 w/ 250k miles.
