Abstract
Abstract An expansible and contractible mobile home, camper or trailer for personal or commercial use has interfitting floor, roof and wall sections, and additional interfitting end floor, roof and wall sections, which move relatively to one another so that it is expansible and contractible in three directions, that is, height, width and length, thereby making it compact and readily transportable yet expandable into a relatively spacious and commodious mobile home, camper or trailer. Means are provided for guidedly moving the sections into expanded and contracted positions, and for releasably securing or clamping the sections in contracted and expanded position.
