Abstract
Abstract The present disclosure is directed to a load carrying trailer which is removably coupled to and transported within a shelter trailer wherein both are attached to a vehicle and pulled by a central draft beam on the first trailer, or if desired, trailered separable by means of secondary hitch; and because of their compactability, lend themselves to providing a mobile shelter for living within when arriving at a shelter site and permitting transport of a powered water-borne craft or motor vehicle on a load carrying trailer to and from the scene of recreational activity without having to disturb the shelter trailer.

Claim 3
Dependent Claim
198 words
A combination mobile shelter and separable trailer comprising a first trailer having a central draft beam supported proximate its rear on an axle having two wheels, a coupling extension on said beam extending rearwardly of said axle, load support means extending upwardly from said central draft beam, a second trailer having an axle supported on two wheels and secured proximate the rear of a frame for said second trailer, said second trailer having flooring of hinged bi-fold sections arranged with the axis of the hinges transversely of the trailer so that the sections fold compactly rearwardly of the wheel axle of said second trailer and kitchen and bedroom furniture fold against and into outer walls to clear the inner part of said second trailer to accommodate said first trailer with its vehicular load, and a unitizing means secured to the axle of said second trailer and adapted to receive the coupling extension of the beam within the means, and means locking the extension within the unitizing means and securing the two trailers as one with the load of said first trailer housed within said second trailer and both being pulled by the draft beam of said first trailer.
Claim 4
Dependent Claim
