Going Tiny to Travel

Wanting to travel the country, Nebraska couple Mel and Carson are looking for a tiny home to take on the road. Their plan is to live and work in their tiny home as they move from state to state. Carson wants something under 200 square feet but Mel's having a hard time downsizing from their 900 square foot apartment. Mel's committed to going tiny but hopes for some amenities of a larger home like a full kitchen, closet and space for their 75 pound dog. Will they agree on how tiny they can go?
