Hop over to my channel to see my old van. I had pretty much the same circumstances as you. Just far less professional when it comes to the carpenter work haha

The new van is a campervan, which might be a little less personal, but the comforts of having your home ready-furnished did make up for that ;)

And being able to stand up and actually socialise inside does increase life quality by far. At the same time I'm happy I started as small as you: This way you appreciate every cm all the more ;)
