RV’s are great for travel, but not so great to live in. They aren’t built to be used every day like a house. Since they’re expected to be moved frequently, the materials used in the construction are lighter weight and often less durable. RV’s can start to look pretty worn after a much shorter time than you would expect with a house. They also aren’t built to be maintained like a house. When was the last time you heard of someone putting a fresh coat of paint on their RV or putting a new Roof on after 25 years. Tiny houses are built just like a conventional house with all the same, or better, materials.
