Abstract
Abstract A wheeled platform having vertically adjustable leveling standards at each corner for supporting the platform in stationary, level position, spaced columns projecting upward from the edges of the platform; top rails removably supported upon the top ends of the columns; and a detachable step assembly to permit the platform to function as a portable porch for a mobile home or trailer. Side rails removably and adjustably supported upon the columns beneath the top rails in vertically spaced relationship also provide containing walls, to permit the platform to function as a utility trailer with the leveling standards raised and the step assembly removed. Some of the columns on both sides of the platform are provided with upper tubular sockets to receive the depending legs of a canopy frame for supporting a canopy above the platform to function as a camp in a vehicle.

Claim 3
Dependent Claim
64 words
The invention according to claim 1 in which said rails comprise top rails and side rails, said means for detachably securing said side rails to said columns comprising loop means slidably and removably receiving said columns for vertical adjustment said means for detachably securing said top rails to said columns comprising fittings adapted to be detachably secured to the top ends of said columns.
Claim 4
Dependent Claim
54 words
The invention according to claim 1 in which said columns comprise a corner column fixed to each corner of said platform, the bottom end of each corner column being internally threaded, an externally threaded leveling rod for each corner column threadedly engaging the internally threaded end of said corner column for vertical coaxial adjustment.
Claim 5
Dependent Claim
69 words
The invention according to claim 1 in which said step means have a pair of upper spaced apart posts adapted to be placed adjacent said two rear columns in operative position, pins on one of said pair of rear columns or posts, and hook means on the other of said pair of columns or posts for detachable engagement with said pins to hold said step means in operative position.
Claim 6
Dependent Claim
58 words
The invention according to claim 2 in which said loop means comprise uniform collars fixed to the ends of said side rails, so that the collars of adjacent ends of said side rails may be fitted over a common column, said collars abutting each other vertically upon said columns to hold said side rails in vertically spaced relationship.
Claim 7
Dependent Claim
79 words
The invention according to claim 1 in which at least two columns fixed upon each side edge of said platform comprises an upper tubular socket, a canopy frame having depending legs on at least two opposite sides of said canopy frame, said legs being spaced apart to correspond to the spacing between said columns having upper tubular sockets, so that said legs may be inserted and received in corresponding tubular sockets to support said canopy frame above said platform
