1920's
Mobile / Motor Homes

The first mobile homes were really homemade camping trailers pulled behind cars. Factory-built models came along in 1926. With each decade, they grew more luxurious with bedrooms, kitchens, and bathrooms. They proved to be so economical that today 30% of new homes constructed are manufactured homes.
