I did a post on steemit on living in a van which might interest you as well:
Its difficult to decide which way to go?. In the end you need some land, so once I get that sorted we will make our choice. With a tiny house it feels more like a home and you have to buy quality things that have a purpose. With a van it's more about the mobile life, which also appeals but perhaps not as long term. Either way getting the land is key I think.
Cheers
Yeah, you're right. A piece of land is a good start. I could imagine if everything is set, discipline is next, controlling our human passion or desire to acquire more, to limit stuffs and balance our day to day living. Its a matter of what we need and not what we want.
Gotta check and read your post 'living in a van'!
