Abstract
A trailer is disclosed which includes a first door with a first hinge configured to allow the first door to operate between an open position and a closed position, and a second door on the opposing side of the trailer with a second hinge configured to allow the second door to operate between an open position and a closed position. The trailer also includes a roof and a trailer tongue with a coupling configured to attach to a hitch of a vehicle. Two or more wheels are provided that are extendable from an up position to a down position. In this way, when the wheels are in the down position, the trailer is lifted off the ground. The trailer can thus change between at least three modes, including a first mode for storage, wherein the first door and second door are in the closed position and the wheels are in the up position; a second mode for ingress and egress, wherein at least one of the first door and second door are in the open position; and a third mode for travel, wherein the first door and second door are in the closed position and the wheels are in the down position.
