I remember a variation of what you're doing from years back, and it's unnerving and not much fun. We lived in a school bus we'd converted from "bus" to pretty swank RV/tiny house... but two of us, + four cats + 2 small dogs in a tiny space was... tricky.

After a while, you settle in, though. It's like living on a boat, except you're on land... which means you can get out and walk around every now and then... MUCH better than a boat.
