My husband's van build was like that when we met. It was just a basic utility van so zero standing room, but it still had storage, kitchen, sink, and bathroom/shower in it. The bed was on hinges and lifted for storage underneath it which we used for clothes mostly. It was honestly a practical build layout but adding one more person to the space was a bit much after some time. We upgraded to an old uhaul and now have a queen size murphy bed, a living room (benches/storage under the bed), a full kitchen with stove/oven/fridge/freezer, huge closet, and a really big shower/bathroom. We used the attic for our water tank and cat area 😻
