Abstract
Abstract A mobile center having a body and chassis with ground-engaging wheels and with an over-the-road capability wherein the body has a roof, sides and ends with the sides being defined by a pair of raisable canopies and with a pair of floor structures disposed within the body and interiorly of the canopies for over-the-road travel. The floor structures can be lowered from each side of the body to provide floors beneath the canopies with powered actuating means for operating one or both of the canopies and floor structures between operative and inoperative positions. Also, enclosures are hingedly connected to the canopies and to the floor structures to enclose the space between the floor structures and canopies to provide additional uses for the mobile center.
