Idk how it’s relavant to them that you are basically a van dweller. As long as you are taking care of yourself (eating healthy, exercising, showing, and whatever else) then it doesn’t matter.

Maybe if there was some treatment that required you to have access to facilities you need in a house but I can’t think of anything. This is one of those times I would omit or just say you live in a house.

Just make sure you’re stashing away some cash in an account so you can replace your ride or put a down payment on a house if you decide you do want something a little less mobile some day.
